Cool,
I had the same problems several times. #1 below was the normal
reason before I put a gas filter close to the carb. Also had the problem
after the installation of the filter when I wrapped the inlet fuel
connection with teflon tape. Had a tiny piece of teflon in a main jet.
Also had an ant in the main jet once. How it got in I will never know.
1. Had crud in the main jets of the carb. Running too lean
as a result. If floored the power valve opens and gives more fuel, bypassing
the main jets causing smooth running. Clean carb and put an inline filter
close to the carb intake.
2. I also had the vacuum advance fail. Not leaking, but the
internal stop broke so that at light load the timing became way to
far advanced. This caused miss fire which backed off the vacuum
and then it repeated. It was frustating to find. If floored the
vacuum was low so not so much advance and it ran fine.
