Well thanks Joe.
Buzz,I'm checking the degrees of mechanical advance in the distributor.
Flop a degree wheel on the dist body,clamp a grips on the rotor shaft,fix a wire pointer,bend for 0 degrees.Hold the [censored] securely,rotate the grips until the avance stop is reached,this one had 15 degrees or 30 at the crank shaft plus 5 more when times at idle.I brazed up the dist cam stop,limited the total crankshaft advance to 22,set the initial timing at idle to 12-14 degrees.
