Good news is, my engine is timed! Bad news, and I can't believe I did this...but I tightened the screw on top of the piston while trying to torque the camshaft sprocket. I completely blanked and should have known better. Now I have to rip off the oil pan I JUST put on and take the piston out. Easy, but still very frustrating.Anyone tried to buy ONE 87mm County piston? Guess I will call BPN tomorrow to see what they can do.
