I have a old 66 mustang that was designed to run on lead fuel.. The proper way to adjust the timing is to advance it as far as you can, then drive it.. If it "pings" when you accelerate, then you need to turn back the timing a small amount. Repeat until there is no more ping. if you don't know what a ping sounds like, then enlist of the help of someone that does. --- Claire Usher <claire_usher71@xxxxxxxxxxx> wrote: > Hi all, > > I've had a really fun weekend out in the Rapier with > the Derwent > Valley Triumph Sports Car Club (yes, I know the > Rapier isnt a > Triumph....) :o) > > Each year they have a 80 odd mile tour through the > Peak District and > invite non Triumph cars too.
