Flying Horse 66cc.
I ran into an issue where the bottom of the piston is hitting the bearing. I always heard a bit of knocking and thought it was normal. After about 2200 kms on the engine, the inside of the piston where the pin slides through, had broke on both sides. So I put another piston on from the same make and it's doing the same thing but not even allowing the gears to do a full turn. So now I'm trying to take the gears off the old engine to rotate the bearings and crank to see if that is causing the issue. I was able to get the drive sprocket off with the puller but the gears did not budge and has caused the threads to strip where the puller screws on to. Any suggestions how I can get the gears off there so I can rotate them?
