This could be a long post but bear with me.
I purchased a Chinese 4 stroke from Stirlingkit last year. Very happy with it until a grubscrew failed on the small gear on the crankshaft which jammed up on the larger gear on the cam side shaft, both gears suffered some damage. After a lot of shaky hands under a magnified light I was able to get them meshing ok. I'm now having trouble trying to get the timing correct. I just set the valves as TDC rocking and ignition a fraction BTDC compression stroke. Motor tries to run but will not keep going. Attached are 2 photos 1 Engine & 2 Cam Adjustment Instructions which I'm having problems following.
Can somebody please help ?.
