Don't go jumping on to the 'heat related' bandwagon just yet. That is if
you're talking about heat affecting the fuel, vapor lock, boiling, etc, and
not ambient temperature. You may just be experiencing the Autumn-time Blues
(tuned for summer, forgot it was going to get cold). Let's start by
answering a few basic questions.
1) How does it run when not up to operating temp?
2) At operating temp, does it run better or worse when the ambient temp is
cool/cold?
3) Is it hard to start when fully warmed?
4) When it is running poorly at operating temp and you engage the choke
(assuming IT is working properly..), does it run better or worse?
These answers will at least give a little direction to your search.
Good Luck,
