Thanks Grumpy. I was reading an article on setting up the 6HP Chonda's as cart motors and the guy had gone to a lot of trouble to pull it apart and physically remove all the bits associated with the governor. I couldn't really understand why he had gone to that length and was wondering if it was necessary or if, as you say, simply connecting a new cable to the butterfly would do the job. I guess I will need a choke cable as well?
I had some personal dealings with Jack some years back. While he was a great driver and knew an awful lot about motors, he wasn't the decent human being a lot of people thought. Sorry to speak ill of the dead but it was a shock to find out what someone I had always admired was really like.
