I took your advice, adam. Richened the bottom end. Didnt do a darn thing to stop it trying to take off, but gave it a stronger, healthier sounding idle.

I want to try and tighten the spring, but I dont have a spare one on hand incase I make a mistake and ruin this one. I was just going to remove it, cut a few turns off, put it back on and re- twist the ends together.

Thats great though im glad I know how it all works now.

Anyone know what the advantage of a 3 shoe clutch is ?
