Hello I have a 2 stroke bike that starts but doesn't accelerate eventually it dies. I've cleaned everything. When I turn the wheel and physically touch the tip of the spark plugs it doesn't shock me. What could it be? The last run I had with the bike was that the bike would decelerate a lil and start to spatter also it wouldn't idle when I'd hold the clutch down. It would work fine one moment then the next moment it would spatter and slow down. It does turn over still and I put a gap in between the engine and the exhaust 1/8.
