hey guys im having a problem with my 2012 wolf 50cc gy6 engine scooter. i took off the cylinder head to swap it out for another because i accidentally stripped the threads in the sparkplug housing, and all attempts to repair it actually made it worse. but i noticed what the problem might be after reading a few threads here. while installing the new head and putting in the cam i actually managed to pull the timing chain forward a few links.. i went over to the flywheel to make sure it was still at TDC and it was so i reassembled it normally but it would not start up. is it possible that i have thrown the timing off?
