hmm what cos piston jammed?? >>> incorrect setting may
cos piston jammed, lose piston ring will do that too, 2T oil not
really a problem... piston expand too fast oso will jammed
up...
what to prevent it>>>> dun sudden whack ure engine to
max if u just started ure engine , make sure ure settin not too
lean or too rich... make sure, must have the present of 2T of
whatever grade,
then always open close throttle when ure slowing down after high
speed... cos remember.... 2 stroke no 2T oil will be fed to piston
once ure throttle is close....
hmm guess like that should be enuf.... heheheh
