You'll have to replace the pickup with a set of points and a condensor, set the gap and then set the timing. A new rotor arm on the top of the cam and the existing cap should fit. Plenty of threads on here about setting timing.
Well, It was the hall sensor after all. Shoved a brand new electonic ignition dizzy in and she fired up. Running lumpy as heck but at least shes alive.
Will do the timing and final tweeks this weekend.
