You can also solder the speed screw adjustment body in the arm. It takes just a touch.

Yes, It's a great engine to build. It will coast 30- 40 revolutions as the norm. I made 1 or 2 minor changes that I'm keeping secret ( how else will I keep my status as a "Miracle worker")? But I'll give you a hint, you have to go on a MAJOR drag reduction effort. I also found out that mine runs much better on Coleman (camp stove fuel) than on alcohol or acetone.
Can't wait till you let us know it's done. You'll enjoy it!

You know you've had a good day in the shop when you have to clean up with a #10 coal shovel!

Engine Maker, I want to earn my selves a nick name to! I will pick you up on that 100+ revs! When I succeed, I want some fancy name. My first build, the Stuart 10V, runs on 0.4psi with no running in, so I’m feeling I can manage it with even more practice. My “thing” is accuracy.
I noticed Jerry Howel wrote something about Naphtha as fuel. Have a bottle I will try. I also got the plans for the Propane demand valve. Like the Propane idea because of the very clean exhaust and no soot.
