Timing of a Kazuma Mini-Falcon 90
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.
