Dave72dt Posted December 30, 2020 Report Share Posted December 30, 2020 I think the part number you're looking for is 637 191. That said, try a parts store that still keeps parts books. Some of the old books have full size illustrations of carb base gaskets. Quote Link to comment Share on other sites More sharing options...

Sniper Posted January 1, 2021 Report Share Posted January 1, 2021 https://carburetion.walkerproducts.com/carter/carter-carburetor-kit-1bbl-bb/ Gives the thickness on the various carb mounting gaskets they offer for the BB. .062" on all of them though, which is about half of your 3mm estimate. But if you are leaking gas like crazy as you say I don't think the issue is the gasket, I am using one of them and mine doesn't leak.

greg g Posted January 1, 2021 Report Share Posted January 1, 2021 That gasket is not exposed to liquid fuel in normal operation. It is an air seal to keep un metered air from being sucked into the intake manifold after the throttle plate. If you have liquid fuel there, it is caused by a needle and seat valve not closing, the float level being incorrect (too high) a leaking float or high temperature percolation. When correct fuel at that point is fully attomized and being sucked through the manifold to a port while the engine is running. Quote Link to comment Share on other sites More sharing options...
Booger Posted January 4, 2021 Report Share Posted January 4, 2021 had same problem with air leak with carb to manifold gasket. cant seem to find metal/felt gasket. made new one with felt/ copper /felt sammich gasket. no air leaks Quote Link to comment Share on other sites More sharing options...
desoto1939 Posted January 4, 2021 Report Share Posted January 4, 2021 The gasket can be thin. It is used to fill in any spaces or gaps between the two metal parts onthe base of the carb and the top of the intake portion of the manifold. And yes you do need the slotted gasket since you do not have a govenor on the car. I just checked on one of my carter original Carb Kits and for my 1939 Desoto Kit the same gasket that you ae showing has an approx thicknes of 1/16. would assume that the same gasket would be used on all down draft Carter Ball and Ball carbs.

ptwothree Posted January 5, 2021 Report Share Posted January 5, 2021 Have you tried a FelPro 8531? NAPA or any good auto parts store should be able to get one. Quote Link to comment Share on other sites More sharing options...
