I'll keep that in mind next time I'm in there. However for the time being, I ran it up this afternoon, red spring and chopped spring rev to same rpm. No change. Removed govenor nozzle, and ran it and it runs perfectly, full rpm is over rev but it has full rev range so I'm still suspect that the governor nozzle is the issue. Did I read correctly somewhere on here that you have cut the red spring in half and used that on either side of the diaphragm instead of using the governor vacuum system?
