Thanks Max, but as you can see from my drawings when you move the cable to the engine stop position the three leg piece drops into the deep vee allowing the poppet to go wide open, but you do not notice this because in that position the ignition has been cut,so the motor stops, if you have the ignition wires disconnected it will go full revs.My idea is to file a slope between the start position and the run position so that a gentle transition can be achieved with the poppet from closed to open and this does away with the governor which effectively does not work. Thoughts?
