And have phased the rotor using a cap with a hole cut in it (one inch hole saw next to plug 1)along with an adjustable rotor. Trigger timing is set at 34, max is 31, base is 19 all in by 2500. Box RETARDS...

Used the adjustable rotor to "Center" the spark on the terminal cap from rotor, its almost ALL on the terminal as dizzy degrees are half the crank degrees: so 12 crank degrees is only 6 rotor degrees which given about a 5 inch terminal radius is only 0.26 inches long pretty easy to center.

Also with MS on the plugs seem alot cleaner and low end seems slightly better...
