Fix for rough idle when hot

I know I have seen a topic here that talks about gas evaporating from float bowel when hot. I think it had a fix to the problem. I cannot seem to find that thread anymore. Can anyone describe the problem and the fix?

Keep the fuel line fron resting against the engine and they make heatshields that go under carbs.

A phenolic spacer helps too.

LxMan1, that's a good tip on the fuel lines. I need to go back and check if any of my line is resting on the block.

Ford_six,

Phenolic spacer ! that's what I was trying to search ! What is that? Where do you install it? What does it do?

It's a plastic/composite spacer that goes between the carb and manifold. Basically, it insulates the carb from conducting the heat of the manifold. I believe that Summit carries them, or you may be able to pick them up at a local parts store. Depending on what you have for a factory installed spacer, you may be able to just unbolt the carb, take out the old aluminum spacer, and install the phenolic one.
