It's new. Shouldn't it be lapped and ready to go ? Anyway I'll try to fix something to put air pressure in the cylinder and see where it leaks. What do you use on these small engines for lapping ?
Before I take the head off I might try adjusting ignition first, that's easier. Right now it sparks a bit before TDC.
But before all that, I have to fix the flywheels. Apparently it moved inward, allowing the lever thingy to hit the cam gear. The flywheel is free and rotating, but doesn't want to come off no matter how I pull it. Both set screws are backed out all the way and the collar on the back is loose. Still it won't budge.
Also the flywheel on the other side is loose. I tightened that. Raphael in the video you mention you fixed this issue. How did you do it ? I imagine every time the engine hits those poor setscrews get a lot of force to resist...
And what would help me greatly is for someone to measure the flywheel on the cam side, how much is the crankshaft inside the flywheel. It's almost flush now and it sure wasn't like that.
