I'll debate you on doing it every other year,been running them since the early 70's,A/B and C body,hardly ever had to touch them.Biggest issue is having someone doing one that isn't familiar with the adjustment procedure.There are about eleven steps,do a few out of sequence and you mess up the balance.As far as burning up,I have yet to see the first.This one on this 71 Dart went untouched for over 7 yrs.
