Grumpy,

Sorry missed the last two numbers 790531 so built in 1979.

I moved the spring to the notch in the leaver and the tension profile is much better see attached picture

Ran the engine, runs steady and revs up nicely. I need to check the high idle speed with a tacho to make sure it is set up correctly.

In th e mean time I'll look for the rack and pinion style control box

Cheers

Mick
