I recently replaced the output shaft on my sons Mini-Falcon 90. Now I am having trouble figuring out how to time the crankshaft with the cam shaft. My magnetor wheel has three marks, T, F and then two other marks. My cam sprocket has two different kind of marks, one is the regular timing mark and the other is a XY stamp. Which ones do I line up with what in order to get it back in time without bending another valve? Any help would be appreciated. My son hasn't had a chance to enjoy his Christmas gift as of yet.

Thanks.

 

Align the T mark on the flywheel with the center of hole or pointer mark. This is TDC, the piston will be at top. Align the cam marks so the valves are closed.

 

It's a Honda clone motor, all you really need is a Honda repair manual.
but for further help.
