so i started my km 23cc as usual and it ran just fine. then i rolled it (small roll) i started driving it then out of nowhere it was like a rocket i had just driven it 3 hours ago so i didnt thing it was to lean. but it started makin a noise so i let off the throttle then it stalled. so i thought maybe it was to lean so i richened it but i cant get it to start. So do you think i might have bent the spark plug possibly during the roll? plz don't tell me i might have blown my motor plz... i have also play with the carb settings like crazy and nothing!

reset needles back to factory setting, and pull the plug and check it for damage, it may have cracked the insulator, check those things first

I've experienced similar mate. My moneys on the plug being fiddlesticked. If it is, make sure the plug lead is ok too (internal spring seated correctly). Get yourself an RPM protector. The standard part is a joke! Got me one ordered from the U.S for a tenner posted.
