When I bought my PI 3 years ago, the previous owner had fitted a fancy rotor arm with a governor mechanism that shorted the spark at high revs.
When I got the car, the governor operated at 4100 rpm, but over time I imagine the springs have got tired, and this has crept down, and yesterday it was down to 3600 rpm which is a bit too low.
I know I could just swap it for a standard rotor arm, but I quite like the idea of protecting a lively but 34 year old lump with a rev limiter, so I would prefer to adjust it back up to 4000 rpm if I can.
Has anybody got instructions on how to adjust these things?
