Neil:
It's pretty straight forward, but you really need a distributor
machine to get the correct specification.
Pin, or solder the breaker plate so it no longer moves. In the
bottom of the dist. is the little plate that restricts cent. adv. movement.
It has a number stamped on it. Use braze to add material, or file to remove
until the dist. maxes out at 30 degrees.
The stiffness of the two springs controls at what revs you will get
full advance, fiddle with these if necessary to vary the curve.
