Re: Mechanical fuel pump, to much psi??

Hard start when warm problems on Edelbrock carbs are solved by putting a heat insulating spacer between the carb and manifold. It doesn't need to be anything exotic. A cheap thin phenolic spacer will do the trick. The reason for this is that the fuel bowl on the Edelbrock carb are centralized and the engine heat boils the fuel off when you shut the engine down. Not a problem on Holley type of carbs since their fuel bowls hang off the ends of the carb body and are not directly over that hot manifold. This is the same reason that original Quadrajet carbs use that thick base gasket that they do.
