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


It needn’t be down to one side worn more than the other, but manufacturing tolerances etc. It’s unusual (unless someone has taken the time and trouble to stone the cam ring) that they are the same side to side, and that goes for any similar mag.
The Technicalities gives a better method of timing than the old Scott manual does; after all what does “points just fully open at TDC” really mean?
