Carbuetor Issue

I just rebuilt my motor last year and have a 1406 carb. . I was having hesitation issues and had 3-4 plugs always looking rich and the others fine. I also put on a NEW rebuilt dist., flame thrower #3 and module.

This year I brought back to my mechanic and we did a compression , leak down, manifold smoke, valve check and everything was fine. So I decided to try a new 1411 carburetor and follow Jason blog to a t. Plugged gutter holes, bought insulator spacer and away I went.

Started the car and found the car with less power and still hesitating? So I pulled off the carb and found the insulator front holes seem to be about 1/32 too big for the manifold? We also noticed that the gasket was soaked and the gutters were full of fuel.

Can anyone help.

Thanks

Dominic

Loud air moving sound within carb with cleaner removed

Posted by Dave Fehrle on March 23, 2024 at 3:23pm 8 Comments 1 Like

While checking my Carter carb with engine running, I took the air cleaner off and there was a very loud hissing sound of air. I placed a piece of paper over the carb and it didn’t move up or down, is this normal?

Vintage Air AC

Hey everyone, has anybody done a Vintage Air AC/Heat setup in their car? I want to bypass the old vacuum setup and go with a Vintage Air Gen 2 model. Before I get started, does anyone have any experience with this? (Which model to go with, do’s and dont’s, etc.) It looks pretty involved. Any and all info/pics would be greatly appreciated. Thanks!

Who rebuilds original AC accumulator dryers for 1964 Cadillac? I have been on Classic auto air in Tampa FL wait list for over a year , There is one on Old air products web site that looks very similar to the original # 21-4214A but states it fits 1962 Gm cars, The one recommended for a 1964 Cadillac is half the length 21-4215A What is everyone using ? I would prefer to be as original as possible. Thanks
