I agree he needs to check out fuel pressure and the needle and seat. He needs to cover all the bases.

I called Holley Tech on this issue and that is what they said too. They said I should install a regulator set to no more than 5 1/2" psi. I did buy one but didn't install it because I also bought a new fuel pressure gauge and it reads a real consistent 6 psi from my carter mechanical fuel pump.

If you have an electric pump with no regulator that could be the problem too.

But the fact that (like mine) it only happens when warm is hard to explain by the other issues. Also my problem only started after a particular fuel fill up in mid february.

Anyway, good luck, hope you get it figured out.

P.S. Let us know what fixes it, I may have a relapse.
