In this video, I have added some weight to each of the governor weights. The pieces I have added are 0.545" diameter brass x 0.100" thick. It does let the engine run at a lower speed, and it does give longer "miss" cycles between hits. This is a very noisy engine, and I think that most of the noise is coming from the governor assembly itself. Anyways, I achieved what I wanted to, thanks for having a look.----Brian
