First Corvair (Wisconsin)

Unread post by maintenanceman » Tue Mar 14, 2017 8:53 pm

First of all thanks for all the info on this forum, its helping me get a Corvair education. this was my grandpa's car, in his passing I purchased it from the family. While I grew up around his (6) Corvairs I do not know much about them (just starting to learn). My plans for the car are getting it running good and after market wheels. I removed the bad gas from the tank and replaced it with 91 octane and sea foam additive to help clean the system. According to the title there has been 10,000 miles put on it since 1986. The car has been in storage for at least the last 5 years. I have taken it around the block a couple of times, it spits and sputters when getting going up to about 2500 rpm then runs pretty smooth to approx. 4000 rpm where it starts to hesitate, could this be because of the cold weather (>30 degrees)? Seems to run great in the heated garage through entire RPM range. So far I replaced a brake line, replaced the air filter and ordered the shop and assembly manuals along with the Clark's catalog (oh and removed the continental tire rack). My next step is fuel filter and possibly carb clean. Also are there more places, other than Clark's, to get parts. Thanks for the great forum.

Looks like a great car! The temperature you mentioned could be related to the running.
Probably first test would be check dwell (measurement of crankshaft degrees of rotation while points are closed) This is done with a dwell meter, which most most parts stores carry. Reading should be around 31-34 degrees.

Next, check timing. The turbo car calls for initial timing of 24 degrees before top dead center. (set with vac advance hoses disconnected)

The weather temperature could certainly cause some issues, and the first thought is that of the choke. The choke mechanism should close when cold, and then open slowly as the engine warms up. To check, pull the air filter assembly and visually check when cold. When cold with the choke plate closed, and then the engine started, the idle speed should be 1400 or so. The choke plate should open a little when first started, If not, fast idle cam on carburetor may not be working.

Let us know your findings, perhaps we can offer more advice.

:wave: :welcome2: Welcome to the Corvair Forum! What a beautiful start for your first Corvair! It appears to be a very well-maintained, rust free 1965 Corsa convertible... and with late model (1965-1969) convertibles, low levels of rust, road salt exposure, and body rot are critically important in preserving the (unibody construction) car.

:dontknow: I would like to encourage you to expand on your initial post and tell us more about yourself, your Corvair, and your goals for the Corvair. If you can describe your personal assessment of your mechanical skills and abilities, that would help 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, Corvair-related knowledge, etc. Helping us to know more about you will help us to write comments to you that are tailored to your needs and experience. Knowing your location is also useful, because knowing where you live can sometimes suggest possibilities.

Nice looking car but please do us all a favor and take that awful continental kit off the back end. That's not helping anything in the looks or handling department.

That is a nice looking car, but I agree with Wolfe - the continental kit should go. The last thing you want is extra weight out back.

First I would not drive a nice car like that in the Winter in Wisconsin. I remember the salt on the roads back there. If you want the car to stay nice it should be a summer driving car.

Since the car is a turbo it DOES NOT have a vacuum advance on the ignition distributor. The distributor has a pressure retard on the distributor and it MUST work to avoid detonation (pinging). Use the highest octane rating fuel available - 91-94 in the U.S.A. In spite of the hysteria about modern fuels, up to 10% ethanol blends will not cause an issue if you use modern fuel line hose - like GATES Barricade brand hose.

Chevrolet revised the turbo carburetor almost every year. Clark's Corvair Parts sells Bob Helts YH book and it's on Amazon - https://www.amazon.com/Identify-Rebuild ... 1426928343
Steve Goodman in Colorado does a lot of Turbo Corvair work and our club rebuilt a 62 Turbo. It ran awful. Finally we sorted out the carburetor per Steve and MOST importantly - we installed a Holley fuel pressure regulator and set it at 2.5PSI per Steve (stock fuel pump is 4-5PSI, but some newer ones are running 8-9PSI) and the car ran great and the fuel mileage improved. The turbo side draft carburetor was first used in the 50's on other cars before being revised for the Corvair. Do read Bob H's book. BTW - the mechanical fuel pumps have had one or the other issue for decades and a lot of use have given up and mounted simple external electric fuel pumps (near the gas tank). The advantage of an electric pump is it overcomes vapor lock issues and after a car sits for some time the electric pump primes the carburetor (modern lead free fuels are more volatile and evaporate easier so "dry carburetor" issues occur, and this was BEFORE ethanol was added).

The first thing to do with a car that sat for a few years is to change the fluids. You've done the gas tank. Replace the brake fluid and use DOT3 that is compatible with any of the seals used over the years. Check the transaxle - if the gear lube is black it will have to be replaced (few seem to change the transaxle lubricant). USE ONLY GL-4, DO NOT USE GL5 OR GL4/5!. GL4 is hard to find now, but you can find Sta Lube GL4 on Amazon. The Sta Lube viscosity is thicker than original so the car will shift hard when cold, but is fine in the summer. If you must drive in cold weather you can use a lower viscosity Ford GL4 and there are some GL4 synthetics, but they are expensive.

When I first got into Corvairs I took my time and found a lot of well meaning folks are mis-informed and give bad advice. So never jump on one suggestion. Read the books and find experienced folks. Find a good club and figure out who really knows their stuff.

About aftermarket wheels - Be aware that the Corvair used a deep backspace rim for the era - so installing aftermarket wheels can lead to issues if you don't get the proper dimensions. I like a 14" tire as the 205/70X14" is the same diameter as the 7:00X13". A 14" rim, 6" wide with a 4.5" backspace is good. Some prefer a lower profile 15" for more choices. Oh - Only Maxxis makes a 13" automotive tire for the Corvair now (185/80X13), but it's a good tire (do not use a trailer tire!!). Supply comes in as batches so availability is hit and miss, but usually a shop can get them in a few weeks.

Here is a list of articles on the "other" forum - http://corvaircenter.com/phorum/read.php?1,268278 that may be helpful.


Good luck and enjoy a nice Corvair.

Jerry Whitt, thanks for the advice. The dwell is 24 i didnt have someone to rev the car to 1500rpm but with a little rev from the engine compartment it dropped to 23.4. I couldnt check the choke plate "opening a little" because i had to keep my foot on the pedal to keep it running. The choke plate was closed when I started it but it did not go to 1400 rpm on start up. When I was able to exit the car (car running with out foot on the accelerator) as it warmed up the choke plate did open. I did not check the timing as I dont have a timing light but could probably borrow one. Just a side note when I went to the local auto store and asked for a meter to check the dwell angle the two guys behind the counter had no idea what i was talking about so I had them point me to the multi meters (before this corvair ,at 36 years old, I wouldn't have had any idea either). Anymore suggestions would be appreciated.

bbodie52 thanks for de coding the the body and vin numbers. Does the a2 paint code mean this car is supposed to be tuxedo black? As far as the salt goes I would not drive it in the salt, it did warm up here in Feb and rained so there was no salt on the road, but was cold when I took it around the block. Also I will check out the north east wisconsin corvair club as I live i kaukauna.

66vairguy thanks for the advice on fluid replacement. The gas is new as stated, the brake fluid is mostly fresh as I had to replace a broken line feeding the splitter in the rear so the fluid coming out of both the rear bleeders is clean. I still need to bleed the fronts, I was able to break all 4 bleeders loose so this shouldn't be a problem. I will definetly look into getting that transaxle fluid and the oil change is definetly on the list, which leads to the next question what viscosity oil to run. This seems to be debated. I want to run a synthetic, but not sure what brand or if the zinc additive is needed. The way I see it, is that the additive cant hurt (your thoughts). The shop manual I have recommends 10w-30. As far as the wheels that will be a future endevor with more research needed. For now I want to get it running good and enjoy it this the summer.

to everyone else the continental kit was the first thing to go and thanks for all the advice I have a lot to learn

:think: The Carter YH carburetor has a marginal reputation and is somewhat difficult to tune and maintain. It is sensitive to excessive fuel pressure from the fuel pump which should be checked. The use of fuel pressure regulator is often recommended. To supplement the factory shop manual, the following book may be helpful in tuning and adjusting the carburetor...
