I run a dual point distributor in my Duster. It gets whipped pretty good. While I have 2 distributors for it (different curves) in all the years I have been racing it the distributor never really falls out of tune. From time to time, usually every spring I throw them in the machine and spin them up. I wonder why I do it. I guess for piece of mind and mostly because I can. I was born when Electronic Ignition was standard. People really [censored] about points... I'm not sure why.
