I believe that the flywheel gear teeth are about 3.75 degrees each .CONFIRMED there are 96 teeth 360/96=3.75 degrees If you get to TDC on compression ,There's an idea, I can count the teeth to verify that turn the flywheel back 8 or 9 teeth ( after you've verified ign. point gap) and twist the advance cam until the points just crack open I tried that already. yes that seems to correspond to the highlighted mark( use your meter ) and you will be quite close to correct timing . As you mention , check with light for full advance . I have a light you can borrow :) . Good Luck , Peter
Don't trust what you see, put a wheel on it and make your own marks.
360 degrees divided by 96 is pretty accurate don't you think?I checked the TDC marks with a probe in both plug holes.I must be missing your point.
Has anyone really noticed on a street Tonti that a 1 degree change makes a noticeable difference ? Peter
I didn't realize Moto-guzzi had a space program Peter
