i just installed a heat insulator gasket between the carb and manifold, had a hard start problem when hot, always smelled gas in the garage, what a differance, starts up now with just a touch of the key, even has more snap to it, idles better, no gas smells, i would recomend this gasket to anyone running a carb. picked it up at local parts store. its made by edelbrock, but im sure other companys sell them, price around $17.00

Not uncommon to need a insulating spacer. What happens is once the engine is hot. after you turn it off the heat from the engine heat soaks the carb. It actually boils the gas in the carb.
Be aware the insulator is a spacer. Different thickness's and shapes,4 hole or open spacers can have an effect on how the car performs. Usually they can move the power band up slightly.
4 hole help power in the lowwer rpm range.
I tryed a 4 hole and a open spacer but without a dyno hard to tell much of a difference if any.
