I would upgrade to the electronic ign. The reason being is smother running due to less variation in the timing. The mechanical advance has some play in it when timing is advanced/retarded. Thus fluctuations in the curves. I recently changed mine to an Ultima unit. It is a cheaper version of the Dyna 6000I(?). This was on my '73 Shovel. I like mine very much. The reason for the change was due to the mechanical advance broke a spring 10 mi. from Boerne,Tex. on I 10. I still had about 200 mi. to my destination at Sweet Water for an AMCA meet/greet. Any way short story long, I had a spare advance, changed on the side of the road and onward thru the fog.
