CHANGING LAG ANGLE DOES NOTTTTTTT change run timing. Over 250 RPM the spring never winds up and trips, its out of the equation. Over 250 RPM run timing is a function mostly of the drive cup used (like a 25 cup etc),,,,,,,,the rotational position of mag in govenor,,,,,,,,,,points gap,,,,,,,,wear n tear n slop.........
If the drive cup is a 35 then FIRST set the lag angle (how much start timing lags run timing) to 35 degrees that way it will fire at TDC at cranking which is 35 slower then run timing DUH
The fine tune the start timing to TDC by movign govenor in flange
HOWEVER MOVING MAG IN GOVENOR DOES AFFECT RUN ANDDDDDDDDDDDDDDDDDDD START TIMING
The middle straight up is 12 1/2 degrees of lag angle and each mark = 5 degrees soooooooooo for a 35 angle move the stop plate 4 1/2 notches. 12 1/2 + 5 + 5 + 5 + 5 + 2 1/2 = 35
UNLESS A 6274 DRIVE CUP IS USED then straight up = 2 1/2 not 12 1/2
SET LAG ANGLE TO MATCH DRIVE CUP,,,,,,,,,,,,,,,,, FINE TUNE MAG IN GOVENOR SO START TIMING IS TDC
This is for Wico XH series Mags used on Deeres BUT I THINK ITS RIGHT FOR YOURS ALSO
