Kevin, I agree with Ken Powell that it still sounds mostly like fuel=20
starvation, probably in the carb. So I won't beat that horse... However, if=
=20
following those suggestions doesn't fix it, then consider:
 Since you have definitely identified temperature as a culprit, that points=
=20
at 2 possible causes: fuel vaporization and detonation. Vaporized fuel goin=
g=20
to the carb could cause a scenario where the bowl cant fill. Also,=20
detonation could behave like what you describe. Maybe you cooling flow is n=
o=20
sufficient.=20
 Doubtful, but a bad could maybe act that way. It's easy enough to test tha=
t=20
as a possibility.
