New Carb Install Question #1324391 09/01/2019 7:39 PM

The main question I have is with all the gaskets I have, I'm not sure what is supposed to have a gasket and what is not? My main question is in between the intake and the carb insulator, is there supposed to be a gasket? I know there's a gasket between the carb insulator and the carb itself. If I put one between the intake and carb insulator, as well as the insulator and carb, there wasn't much thread for the nuts to thread on to, which leads me to believe there isn't supposed to be one between the intake and carb insulator. The other reason why I'm questioning it, is because when I put the carb insulator on the intake, it's not 100% flush and I'm worried there will be an air leak. Thank you in advance for your help!

I put a gasket between the insulator and the intake manifold.

That will probably give you just enough extra stud length to use a gasket on both sides of the insulator. It might not be absolutely necessary, but it probably won't hurt, either. Just be sure not to block any vacuum passages with the gasket(s). If you remove the studs, you can also draw-file the top of the manifold or use a disc sander on it to be sure it's flat before re-installing the studs or putting longer ones in.

Good carburetion is fuelish hot air The most expensive carburetor is the wrong one you attempt to modify. If you truly believe "one size fits all," try walking a mile in your spouse's shoes!

Was just wondering if anyone had any success with those Chinese carbs....Gotta beat the tariff increase! Well Jerry gave me 1/2 of the answer....What type/model Carter should I be looking for, and would it be a 'plug & play' will the factory air cleaner fit?

This includes 216, 235, 261, GMC, Chrysler Spitfire, Ply-Do, Ford 223, Pontiac 239, etc. There really is no universal replacement carburetor.
