Re: Miss and rough at idle
With all the help I received here on this post, I wanted to share the outcome! On Saturday, I replaced both primary carbs with a SET that a fellow club member built with bases, tops, and venturis that were identical and for a 65 . When they were installed, I got a smooth idle at 850 rpm and when th...

Re: Temp/press warning light is on
It is because someone has removed it and capped the spot where it goes with a plug. The little plug in your photo under the piece of rubber fuel hose. This rubber fuel hose should not be there either. Use of rubber fuel hoses in the engine bay is a significant fire hazard (particularly near the belt...

Re: LM Convert Unibody bottom Pictures
It is a 5" tall by 5-6 foot long u-channel that welds into the center of the rocker panels attaching rocker step plate area to the bottom of the outer rocker panel along the rockers full length. Not visible from the outside unless the ends of the rocker boxes are rusted away at the wheel openin...

Re: excessive crankcase pressure
Are you sure the PCV valve is installed the correct direction and plumbed properly (there must be a connection to atmosphere ...air cleaner off the small port on the PCV tube)? If it is I would say you have an internal engine issue like worn or broken piston rings or a hole in a piston etc. How are ...

Re: Rear brake lock-up
Problem is likely on the right side. Adjustment side to side is perhaps way uneven or there is some issue with movement in the right brake. A pull is almost always the other side brake on that axle not engaging at the same time. Re-bleed L first then Right. Look for shoes installed incorrectly (shor...

Re: Temp/press warning light is on
Check it out by disconnecting the wire from the switch then start the engine. If the light is out then the switch is the issue...either that or you have low oil pressure (usually the switch is the issue in this case). If the light comes on and stays on with the switch disconnected, then you have a s...

Re: LM Convert Unibody bottom Pictures
Everything in the car adds to stiffness, particularly any welded panels. Uni-body construction uses the entire body to add to the vehicles structure. The biggie in late convertibles is the center (extra) piece in the rocker panels and same in the hinge posts.

Re: Engine Troubles... Please Help
Checked my spec book for 110 engines. Compression for a 1965, 110 is listed at 9:1. With stock compression ratio, the compression readings should be around 135 pounds. The thought process then asks why the pressure would be a little higher. Carbon build up (?) really thin head gaskets (?)special pi...

Re: Engine Troubles... Please Help
The compression readings of 140-150 seem a bit high. Atmospheric pressure is usually around 15 lbs per square inch. This means a compression rating near 10:1. You noted “pinging” and with this ratio, octane rating becomes an issue. You said you were at “Wits End.” Just had to respond! Sent from my ...

Re: Engine Troubles... Please Help
Black on one bank I would be looking for flooding or somehow overly rich carb on that side. Compression numbers are excellent.

Re: Fuel Pressure and Stalling
Well I feel real stupid about now.... The passenger carburetor did not have either of these connected. I was looking all around and just didn't see it. In fact, the wife saw it. :tu: Capture.JPG Capture1.JPG It seems to idle fine now and at stops and cranks as expected. No gas smell in the new oil,...

Re: Engine Troubles... Please Help
Sorry Blaze missed your comment about retarding no help. I would do a compression test before I jumped back into the carbs. If you are going to re-gap the plugs that is the perfect time. Compression gives a very good indication of the engines overall condition. You may indeed be able to confirm or e...

Re: Engine Troubles... Please Help
Compression test is not likely to show an issue, BUT, it is easy to do and if it does it can save you headaches looking in other places. Making sure the timing is at or close to spec is also very easy to do and actually could be an issue to cause your problems as could flooding. Always do the simple...
