Cliff notes version from my previous post.
96 400cc 2 stroke, oil injection failed, motor overheated, blew a hole into the piston.
I got the new piston head today, and replaced it. Was able to get the old one off and the new one installed without pulling the entire motor.
I got everything back together, it turns over, wants to start, but just won't.
Stupid me forgot that the crankshaft and such were moved all sorts of ways, and the timing is probably off.

I've always been weak in anything timing related. Does anyone have any pointers they want to share?
I already know I have to remove the pull start cover, and pull the flywheel off to access where the timing is done.
From that point on, I really don't know what to do.
