Re: Chrysler 120 Force Timing
30 degrees before top dead center at wide open throttle.
Chrysler made Chrysler outboards. they sold out to Brunswick AMF and the name was changed to Force--the engine was exactly the same. Mercury bought them, kept the engine the same for a few years, then started to change them for a few years, then finally phased them out. So some later model Mercury/ Force engines are different.
