I was going up a pretty weak hill and I slowed down to go around a rock when my sp370 died. I whent to kick start it..turned over with its normal compression..didn´t start on first rotation..normal..on the second rotation I hear a snap sound and the kick starter locked up..wtf?..I put it in first rolled it back and forth..the kick starter loosened so I tryed to start it again snap!..then it locked up again!..when I push on the kick starter with my hand it sounds loose inside the motor...if any one can give me some ideas on what I can do it would be much appreciated!
