Got my distributor fixed, now mapping the ignition timing vs. RPM vs. load using the handheld trigger.
I can retard/advance the ignition timing at every 300rpm increments (or 500rpm increment if you wish) (15 steps i.e. 0 - 4500rpm) vs. load (throttle). Here is a picture or two :
and here ive also fitted the 3-3/8" Sun Pro Tacho on the column (can't fit on top, no clearance)
