Gary, look into a mech advance limiter plate from FBO. plate/spring kit 25$

makes it super ez to recurve the mech advance.

I got mine dropped on the 18* slots with the initial at 14* for a total of 32*

got the 440 with whiplash plate dropped on the 0* slots to lock it out for no mech advance.

I myself run a pertronix points conversion/flamethrower 40,000 volt coil in a point dist recurved with FBO plate. super simple,cheap with no BR or ECU.

I just tape/hide the unused plugs on the harness for a clean look under hood.
