hey everybody,
I purchased a brand new 2 stroke engine about a week ago, i was driving at medium throttle, when there was a loud bang, the piston got two good holes in it and is completely trashed. the housing had a small amount of scoring by the intake. i bought a new casing a gasket and piston. any idea how this happened, anything helps thanks.

yeah there wasnt anything missing no bolt or anything, i ordered another piston and cylinder, i've been doing research my guess is the chinese piston was crap and i just pushed it to hard and took a chip out which then caused the other hole, by slide do you mean the choke?
