welp?

I did my carb and it was great and then it got some new crud from the tank.

but if your carb ran great then your friend is right.

Wind 'em up and it stutters?

Hot coil break down?
does it do it when cold or just hot?
does it help if you pull on the choke? when its crapping out or does it just make it run messy

it only does it when i rev up the engine, so more rpm, which will cause more heat, so hot coil break down sounds like a possible option.
