Hello from Palm Coast Florida!!
Hey everyone:
Just picked up a really nice red 1964 Chevrolet Corvair Monza last night in Daytona Beach. I've been wanting a Corvair for a long time and I got one of the best models!! It sat for a while in dry storage on and off since 2011 with the rest of the guy's collection, including his dragsters. I feel I need to figure out how to remove or flush the fuel tank as the fuel looks dark at the 'filter that used to look new' LOL..Maybe these tanks have a drain plug. Has an idle issue as well, ( not sure if tied to the fuel) but, it idles fine and smooth with a little pressure on the gas peddle.Anyway, body and floors are like new but minor mechanicals need attention. I'm ready to start dropping any improvements into this fine ride. Anyway, thanks for having me!! Scott

Re: Hello from Palm Coast Florida!!
welcome! There is no drain plug on the fuel tank. It is pretty easy to drain, however, as the fuel sender on the right side bottom of the tank connects to the main body hard line with a rubber joiner hose. open this connection and drain the tank thru the hose. Idle issue could be due to old fuel and I would certainly drain old stale fuel and refill with fresh premium fuel (Corvairs really need premium anyway) and see if that fixes it. If not there are likely deposits in the carbs from sitting and cleaning and rebuild of the carbs may be needed (simple carbs, pretty easy to rebuild using the shop manual). Manuals and parts are available from Corvair vendors, the largest of which is Clark's Corvair Parts who have been in the Corvair parts business since the 70's.
Corvair guy since 1982. I have personally restored at least 20 Vairs, many of them restored ground up.

1964 was the year of several upgrades, refinements, and introductions...
- Front suspension stabilizer bar on all models.
- Rear suspension transverse leaf spring and coil spring rate modifications to improve stability and handling of the rear swing-axle suspension.
- Engine displacement increase from 145 CI to 164 CI via long-stroke crankshaft. Associated horsepower increase to 95 hp and 110 hp.
- Introduction of lightweight magnesium cooling fan to improve fan belt reliability.
- Improvements in Positive Crankcase Ventilation (PCV) system over that introduced in 1963.
- Brakes were improved with finned rear drum.

I would like to encourage you to expand on your post and tell us more about yourself, as well as about your Corvair. Your personal assessment of your mechanical skills and abilities helps a lot. Members of the Corvair Forum love to be helpful in assisting other Corvair owners with technical support and advice, but it helps a lot if we have some understanding of your technical background and mechanical abilities, your Corvair-related knowledge, etc. Helping us to know more about you, your Corvair, and you plans for your Corvair will help us to write comments to you that are tailored to your needs and experience. Knowing where you live may also help, as your location may suggest some possibilities or solutions.
The link below will provide you with a list of useful websites that are Corvair-related. Some of the links will lead you to an extensive technical library that will allow you to download shop manuals and other technical references in Adobe Reader (.pdf) format at no cost. There is also a link that will help you to locate nearby CORSA (Corvair Society of America) club chapters. While the Corvair Forum can be very helpful as you work on your Corvair, having local friends and contacts in your region who are knowledgeable about the Corvair can also be very helpful. These family-friendly CORSA club chapters often offer picnics, group scenic drives, technical training and assistance, car shows, and competition events that can greatly enhance your enjoyment of Corvair ownership. You will also find a list of essential Corvair parts suppliers.

Recommend you download a free copy of the full 1961 Corvair Shop Manual and the 1964 Supplement - Chevrolet Corvair Shop Manual using the above link.
A lot of things can affect the idle speed. Does your Corvair have a manual or automatic transmission? Unless your Corvair's distributor has been upgraded to include an electronic breakerless ignition system, it still contains ignition points — and the switch contacts in points begin to burn and decay with each opening/closing the day they are installed. Decay of the contacts can affect the Dwell setting. (Dwell angle is the amount of time (measured in degrees of distributor cam rotation) that the contact points remain closed. Initial point gap determines dwell angle). A change in Dwell affects the ignition timing, and a change in timing can affect the idle speed. It is important to check the condition of the points and the current Dwell setting. If the points are worn, they should be replaced and correctly set. Then check the timing. Then adjust the carburetor idle speed/mixture and synchronize the carburetors — all in that order. A simple tuneup may correct your idle speed problem. The videos below — along with instructions from the attached shop manual section —will help to guide you.
This tune-up chart is from the 1965 Corvair Chassis Shop Manual. The specifications on it also apply to the 1964 110 hp engine. I have also attached a copy of the 1964 Supplement - Chevrolet Corvair Shop Manual - Section 7 - Engine Tune-Up to guide you.
The timing range of 12° - 16° BTDC gives you some variation to tune for optimum performance for your engine and driving conditions. With low-octane Regular gas your best bet is likely to be on the low side (12°) to prevent detonation (pinging) under acceleration, when driving up a long grade or in a heavily-loaded vehicle, and during hot weather conditions.
Watching the video presentations below helps to provide insight and understanding about proper sequencing of the tuneup steps and procedures. Skipping around can insert obstacles and problems with getting the engine properly tuned.

Re: Hello from Palm Coast Florida!!
Thank-you for the info! I found that the idle screws weren't even engaging the stop levers so I turned them on each carb and it idles when I start it now but it sputters off when it warms up I spose, because the 'choke opens' maybe. A friend told me that the fuel may have a preservative in it and that would darken it. I've got to flush that tank. I have a lot to learn but I've restored cars and built engines since I was 17 and I'm 57 now. I've got a lot to learn about these engine. I've owned a few Volkswagens in my high school years and I'm a 1/10 of the way there in knowledge of similar set-ups... LOL...
Anyway, I'm a shade tree photographer also and my original photos are too big as they are 'fine' 5 mb size for zooming in and cropping. I do a lot of aircraft photos over my home, etc. since a National Guard base was built 3 miles behind us next to our airport. My home is inline with the east/west runway which is used as the primary runway. I've gotten some beautiful aircraft photos.... even the jumbos that are 25 miles up. I had to grab my small digital Kodak and got a few. I will have to go to my photo reduction site for my other photos before I can post them. That one photo prior was one of the AD photos. Again, thanks for all the info! I'm sure I found the site I need! I never knew the Corvair club was this big!!!

Re: Hello from Palm Coast Florida!!
Could the apparently dark, red-tinted fuel and material in the fuel filter element be rust particles suspended in the liquid from an old, decaying fuel tank? If it is you may want to refer to my previous post to look at the Clark's Corvair Parts replacement fuel tanks. The cost of a new tank is relatively small. If you decide to replace the tank, consider the mounting hardware, fuel nozzle inlet hose and clamps, fuel gauge sending unit and gasket, etc.

A detailed description of the automatic choke system is provided on Page 8 of the attached DELCO ROCHESTER - Models H, HV Carburetor Service Guide. About half of this guide is written to provide a functional operating description of each carburetor subsystem. A good understanding of the carburetors will help you with troubleshooting, repairing and adjusting the fuel system. There were three different choke designs used in Corvairs: An early 1960-only design that included a choke system as part of the air filter system, a manual choke with a driver control knob/cable in the passenger compartment (1961), and an automatic choke system that was implemented in 1962 and remained largely the same through 1969. A description of this Model HV Choke System begins on the right side of page 8.64CorvairMonza » Thu Nov 21, 2019 11:53 am

With the engine cold, depressing the gas pedal one time moves the throttle linkage on each carburetor out of the way and allows the fast-idle cams to move into place. Each fast idle cam would hold the throttle control lever away from contact with the idle screws until the engine reaches operating temperature and the choke mechanisms disengage automatically. At that point the idle screws determine the amount that each throttle remains open to establish the warm engine idle speed.
To adjust the throttle idle screws, the throttle cross linkage between the right and left carburetors is temporarily disconnected on each side. The initial preset setting of the idle speed screws is a mechanical setting of 1½ turns clockwise after initial contact with the throttle lever linkage. In the tune-up video, the use of a strip of paper as a feeler gauge is recommended to detect when backing out the screw just reaches the point where the screw tip releases tension on the strip of paper. Then, each screw is screwed down (CW) 1½ turns, so that a preset idle point is established and is exactly the same on both carburetors. (This is done with the chokes disconnected and disengaged to prevent interference from the choke fast-idle mechanisms). With the engine timing set first, the warmed engine idle speed is measured with a dwell/tachometer. If the idle speed screws need adjustment, the same amount of adjustment is done on both carburetors to keep them in-sync. To obtain a more-accurate synchronization between the two carburetors, a vacuum or airflow gauge may be used (like a Uni-syn gauge) is placed alternately over the throat of each carburetor on the idling engine to measure airflow through the carburetor, and minor corrections are then made at each adjusting screw to obtain a correct engine idle speed while maintaining synchronization between the two carburetors.
The Uni-Syn Carburetor Balancing Instrument is a tool that I remember as far back as the 1950s and 1960s. It was designed for use in multi-carburetor automobiles, motorcycles, etc. that were initially common in European vehicles, but were later found in American vehicles like the Corvair.

Re: Hello from Palm Coast Florida!!
If there is any rust even moderately significant debris in the tank, my take is just bite the bullet and replace the tank. Yes there are rust convertors and sealant etc, but these also mean significant work and cost that could be used toward a new tank setup that should be maintenance free for years and years. Debris in the fuel always makes carb issues eventually as can sitting for long periods. I have flushed out and or sealed old fuel tanks before but if they were not really really nice to begin with the results were hit or miss (back when there were no new tanks). I have also seen a number of sealed tanks that had issues due to sealant failures. Tanks were either a deep pile of goo on the bottom or even what looked like sheets of latex that had peeled off the inside and pile up in the bottom.
I would also recommend exchanging the plastic fuel filter (not stock), for a metal one (also not stock but a good idea to use a filter before the engine), simply for safety reasons. A steel filter is not likely to flex and break off a nipple, nor is it as prone to impact damage from road debris.

Re: Hello from Palm Coast Florida!!
Yes, I wish to replace the tank. I don't believe in rust converters and interior coatings that fuel will cover and deteriorate over time. I was just talking with my neighbor about that fuel issue who owns a mechanics shop and the one who trailer'd it back to my house after we went to get it 30 miles away. I did suck out a gallon and a half of the fuel into a semi clear water jug and the fuel was orange but no particles so far. I'm going to get a better hose for the job of emptying the tank to make it lighter to pull. Thanks for all the info.

Re: Hello from Palm Coast Florida!!
empty the tank by removing the output hose on the Right lower side of the tank. Route a spare section of hopes to a bucket...of course the front end or car will need to be raised. If you then remove the fuel sending unit you can peer into the tank some (inspection mirror helps) and see how it looks.

Re: Hello from Palm Coast Florida!!
Been wrenching on cars since I was 16 years old. My first car was a 62 Volkswagon convertibe when I was 16, 2nd> 1970 VW bug, 3rd> 65 Mustang Coupe, 4th> 73 Buick Skylark, then 70 Mustang Mach I, then 74 Dodge Dart, then 1967 Chevy Impala, 1964 Cadillac Convertible, 1965 Chevy Impala RS, 1971 Chevy El Camino SS, Pontiac Fire Bird, etc. etc......... I'm a seasoned mechanic and very mechanically inclined. I can fabricate pretty much anything I need if I have too. But I prefer to buy what I need.bbodie52 wrote: ↑Wed Nov 20, 2019 11:01 pmI would like to encourage you to expand on your post and tell us more about yourself, as well as about your Corvair.

Have had a lot of cars up to the present and restored quite a few. I had a 1973 Olds Cutlass fast back and dropped a Buick 455 into it... I love to customize and improve. I have pretty much all the tools I will ever need and if i don't, my buddy/neighbor owns his own automotive repair shop. I consider myself a shade tree mechanic and I'm a perfectionist. I built an 800 sq. ft. shop just for working on my rides. I'm 57 now and I'm loving what I'm doing. I'm also a mig welder and retired due to a motorcycle accident in 1998 where I messed up my back when I slammed my bike into a car that rolled through a stop sign early in the morning across my path on a highway I was on, doing 60 mph. Thank goodness I can walk and function ok, but it can get rough sometimes.
On my Corvair I will change out the gas tank and all related items, change out all springs and shocks. The carbs are new, I'm told but, they don't look it, but they work fine. I would like to find a carb conversion manifold where a two barrel or small 4 barrel might supply both sides through the intake like on the Spyders. I'm also going to find some sporty aluminum wheels. My favorite would be the old school cyclone, aluminum slots/rally, or Cragar wheels. I don't want to go over 14" tall and 13" is fine with me. I also want to convert all to disc brakes.
This is also my first car with a one piece rubber window insert and I've seen tips on installing them with a pic of rope pulled to bring the flap over the metal,but I need to go research more because there is a spot that may soon need attention near the pass. side rear window. I hate to let it go for too long.
I live in Florida ( Originally from Vicksburg, Michigan)where we can work out doors in our bare feet all year around LOL... Palm Coast, Florida to be specific. And this was just to answer your question so I'm going to refer to my new thread now. IF you could transfer some of your info here to that thread, I would like that so I didn't have to run around looking for info.
Thanks, Scott

Re: Hello from Palm Coast Florida!!
If you are giving consideration to converting to a center-mounted 2-barrel or 4-barrel carburetor, there are some drawbacks and issues... I suppose there are reasons why they are no longer manufactured or sold new and the approach has largely been abandoned. The recent post below addresses some of the issues and problems to consider. Reading it may provide you with some "food for thought".

There is an EFI (Electronic Fuel Injection) approach, but it is somewhat pricey. Click on this link to read about it and a DIS (Distributorless Ignition System) that has ben developed in South Carolina and is marketed by Clark's Corvair Parts. This is an approach that I am giving serous consideration to for my 1966 Corsa convertible.

An upgrade for your distributor to an electronic breakerless system may be of interest. There are upgrade kits using magnetic pulse or optical systems to replace the points and condenser. (I tend to lean toward the optical unit, which has fewer problems and issues than the Pertronix magnetic pulse system). However, a new Stinger distributor hit the market a year or so ago that appears to be a better choice than retaining the older, worn original Corvair distributor. In any case, the link below should be helpful if you want to switch to the more-reliable, maintenance-free ignition system approach...

Re: Hello from Palm Coast Florida!!
The 164 CI, 110 hp engine in your Corvair was introduced in 1964 and has a good reputation for decent street performance and reliability. The 110 hp engine continued to be offered in Corvairs through the end of production in 1969. From the cylinder barrels on down it is essentially identical to the 140 hp 4-carburetor engine that was introduced in 1965 and was standard in the Corsa and optional in the other Corvairs through 1969.
This will give you some idea of the differences between the 140 hp engine and the 110 hp engine.
140 hp vs. 110 hp...
140 hp Heads...
- Same high-performance camshaft on both 140 hp and 110 hp engines. Low performance camshaft in the 95 hp engine.
- Same 164 Cubic Inch displacement with same bore and stroke on all 1964-1969 engines.
- Stronger, nitrided crankshaft on the 140 hp and 180 hp turbocharged engines. (Nitriding is a heat treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface).
- On the 140 hp engine, a 4x1 carburetor arrangement, with two primary and 2 secondary 1-barrel carburetors, connected with a progressive linkage to open the secondary carburetors as you approach full throttle. (Equivalent to a 4 barrel carburetor on the 140 hp engine, vs. a 2 barrel carburetor (2x1) on the 110 hp and 95 hp engine).
- Dual muffler, dual exhaust with larger exhaust ports and larger exhaust manifolds on the 140 hp engine. Single exhaust on the 110 hp and 95 hp engine.
- 9.0:1 Compression Ratio in both 140 hp and 110 hp engines. 8.0:1 CR on the 95 hp engine.
It's all about better breathing at full throttle at the high RPM ranges. At lower RPM the big valves and dual exhaust don't make much difference, and the secondary carburetors are not open for business.
