Timing check - Look on the blower housing for a little round plug, if you can find one, otherwise, roll engine to exactly TDC and scribe reference marks on flywheel and blower housing, then, turning flywheel backwards, move it back 10 degrees (or 5 degrees if you want more precision) , scribe another mark on blower housing, rinse and repeat until you have marked off 30 degrees BTDC and then just hook timing light to ignition as usual, check timing. Adjust timing by slightly loosening the breaker points set screw and change point gap until you have timing where you want it.
.020 point gap sets the timing "just about" where you want it, but you can tweak the timing by changing point gap.
Normally .020 does the job, but Ive been known to tweak them (seat-of-the-pants timing adjustment, didn't use a timing light at all in later years - just adjusted points while engine was running til it ran where I wanted it to.. - Kind of like old school auto techs that could set a car engine's timing "by ear" without bothering with timing light. Long as engine runs perfect where you want it to, timing isn't critical.. but in modern day EPA compliant engines, just cant do that anymore..) - Would end up with point gap between .016 to .023 depending on how I wanted to adjust performance - but "seat of the pants" adjustment only comes through years (30+) of experience working with those engines daily.
