The Chim was ticking over at approx 1500rpm.
Occasionally when hot it cut out.
Just taken the advice of so many of you and cleaned the fabled stepper motor, removed a thin film of sooty deposits with a cloth, replaced and it feels like a different car, just wonderful
Based on my experience, took no longer than 15 mins and can reccommend it to all, so what you waitin' for?
Thanks to previous stepper motor contributors.

I understand that the stepper motor was preceeded by an adjustable grub screw on earlier V8's such as 350.
