I'm looking to get my timing set today after replacing most of the ignition components. I looked in my manual and it says the timing settings for this motor are "4500 Mark". I'm assuming at 4500 RPM its supposed to be at a mark on the flywheel. The only thing is my flywheel has TDC and degree marks going up to 36* advanced. So I don't know what "mark" they are referring to. Does anyone know what the total timing advance should be on this engine? Thanks! Christian
