My motor was running fine for 5 minutes and I dinta know what happend there was a wire noise and then it powered down. Tried to turn it on again. The motor turned but won't get going. After two more pulls the fly whell locked. Something must have idk broken or bent but I noticed that the flywheel wheel is pulling on the throttle arm. I played with it a bent ( spoon the fly wheel back and forth) and it un locked but when I tried to pull start it again after two or so turns it locked up again. I still have compression and it sounds like the motor wants to turn on but it just locks up. Any idea what I can do.
