Det står så här "top dead center" så då borde den vara exakt i 12 läget.
Har aldrigt bytt någon bara läst mig till det
Your Saito engine will tollerate a slight mis-timing of PLUS or MINUS one tooth on the camshaft without adverse effects. If it's minus one tooth, you'll get a little more torque. If it's plus one tooth you'll see a little more RPM but you'll have to lower your prop pitch since you will loose some torque. It's BEST to have the cam timed properly!
http://tech.flygsw.org/sick_saito4.htmAssemble the cam gear lining up the timing mark at the “6 o’clock” position.
The crankshaft must be positioned at the “12 o’clock” or “top dead center” (TDC) position.
