HOME and how to join Forum Open Area General Scott topics Ignition Timing On 1930 TT Rep Re: Re: Ignition Timing On 1930 TT Rep


Scott ‘s own manual say’s , set the engine to TDC with the ignition lever in the retarded position ,then set the mag so the points are just fully open, lock the magneto sprocket.
If the cam ring is worn this can be checked with a degree disc on the mag sprocket and any allowance made to compensate, but why should one lobe wear more than the other?
