Default Thick carb gasket why??

[QUOTE=Vette5311;1607719147]I use one of these. It’s about 1/4 inch thick so since you don’t have stock intake best check hood clearance as you may have to run a bit lower air cleaner.




what is the purpose of the thick gasket??? Thanks. Let me know

Not just thicker but the material acts to isolate engine heat from carb. Avoiding all sorts of heat/carb related problems.
Fuel boiling in float bowl, heat soak after sitting etc.

Its gasket like material but is a Carburetor Space designed to reduce heat transfer in to the Carb and lessen Fuel Percolation, Vapor Lock, etc

It sometimes requires adjustment of Primary Jets as it *Can* weaken the draw on carb venturies. Not sure it really will at this thickness.

Default Thick carb spacer

Does anyone have a part number on this spacer? I have the Edelbrock (i think 2701. ) intake and Holley db pump (not sure on size). Thanks.

Been a minute but I think I got it in a Holley Heat Shield Kit. With spacer and an aluminum heat shield.

Maybe look at Summit or Jegs etc

I had a similar problem when the car got hot. Also it was very hard to start after it was run and turned off for awhile. I found the carb float was set too high. Readjusted it to 1/2 inch and solved the problem.

If pumping the gas kept it running I’ll take a close look at the pin on the fuel pump to see if it’s walking out of the slot. I’m betting on fuel.
