boiling fuel

DU: Have you thought about the heat deflectors that Holley makes? Their footprint extends out completely underneath the bowls of the carb to deflect the heat coming off the intake. They are only about 1/4 in. thick, but I am running 2 of them on my 2x4. Jegs carries them.

If you need to trim a little, they are easily trimmed on a bandsaw.

Give it a look! Bob

John, your problem does not sound like heat related fuel issues. It sounds more like the ambient temp conditions are requiring a retune on your carb. Either that, or your fuel bowl level is too high or you have a stuck float. It really sounds like you need the carb tuned correctly to me.

FWIW, I have a MR intake, metal turkey pan, Lemans Holley carb, steel fuel log, steel fuel lines, and just about every other poor scenario you could have on a motor and I have no problems with heat related carb issues.
