Just a quickie, I was messing around with the old stato, and whacked on a carbi I rebuilt, when I was connecting it all up I realised that the distributor didnt have a vac advance module? it look to be after market electronic dizzy, has a red anodized control box wired to it HEI coil etc, but no vac advance.
Question is what difference will this make to the engine? would this have anything to do with the old girl running hot at idle for extended periods of time buy affecting timimg? Had a quick look over the out side and didnt see anywhere that looked like a spot to fit one (but didnt look that much so could be hard to see?)
