So I couldn't turn the back wheel the motor was locked up I took apart the top end and it was seized I had the oil mixture perfect I've had several of these engines and know alott about repairing them so after I tore it down there was a staple from the box inside it and got jammed in the piston I put it back together and cant get it to fire for the life of me tore it apart several times bought all new stuff coil cdi caurb still nothing has spark and gas no air leaks just wont run heglp
