Harry, It bugs me that some of the guys at Mid-South will leave their lokies simmering in the yard while they wander off to chat with someone. Meanwhile, the safety will let go a few times before they decide to stroll back to the engine. I checked one that had no attendant present a couple of years back and was about to turn on the injector when the owner finally drifted back. That is one of the advantages of propane firing, you can turn off the fire if you want to wander about the meet. Possibly my automatic gas control valve will allow me to keep the F&S hot without popping the safeties. It worked perfectly in static tests last week. Indeed, if I had a Walschaerts gear on one of my engines, I would pin the return crank to the pin once I got it perfectly set. Meanwhile, two of my engines have no valve motion at all to worry about and the other three are Stephenson's. You gonna have the TICH chassis rolling by the meet? You got a little over 4 weeks to get her set up so you can drag it in for bragging. Jesse MODEL ENGINEERING DISCUSSION LIST.
