Finally got it started after a mag cam regrind at SRM ,it was 35 degrees one side and 24 degree the other! First time running scince 1974
Did you refrains the cam followers also or just the cam? The cam followers usually wear quicker than the cam... especially on the pre units.
I think he is referring to the cam in the magneto.
Doh. A miss read. Makes a lot more sense now ::)
