i don't now what happened, what i know is my setting is still rich and i don't abuse my engine by pulling the throttle in a long time, not to mention that our track is small so there are no long straights. it's the 2nd time i encountered this. the same problem the same engine where i first broke the original crankshaft, now it happened again. i know there is something i'm doing wrong, i just know what that is.......

... Ooopss
Most common engine part that could be broken is the con rod. Usually after 3-4 galons it will deveoped too much play. Small detonation or bit overeving will broke it.
But if broken crankshaft, only too much overreving (higher than states in the manual) will broke it. Or you have a mechanical / installation problem.
Can describe where is the exact spot that cut in 2 ?
