I have a poulan 3700 that when cold runs great but once warmed up it sounds like the ignition coil is failing. It wont take full theottle. It keeps bumping. Its not hitting rev limit because its low revs. And when you let off the gas it dies. It will run fine for 10 minutes and then start acting up. It has a clean carb, tuned, and new fuel lines. Whats the consensus here? The spark plug gap is correct, and the flywheel gap is as well. Ill try and post video later.
