Hi Dave,

Does it matter if you insert the cam gear in at 6 or 12 o'clock when the piston is at tdc? Reason I ask is because if you rotate the crank 360 degrees and had installed the gear at 6 o'clock, you end up with the piston at tdc and the cam gear at 12. If it does matter then, at which part of the 4 cycle do you install at 12 o'clock?

FYI I run a YS 1.20 and had problems with the first start of the season. I had cleaned the engine and reassembled it. It started up but wouldn't do much past idle. It actually sagged a lot then quit when I gave it some throttle. I had installed the cam gear at 6 o'clock thinking there was no difference given my question above. When I tried to start it again, it wouldn't even kick. After it cooled down, I tried it again and it started up but with the same problems. Tried to start again...no dice. Let it cool down and it started, but, with the same problem.

Thanks!

John
