You are neither the first nor the last that's done that. I did the same last week except I flipped it back quickly and the engine didn't die. The remote kill is a good feature on any engine, including glow, just more difficult to do with glow.
Regards to richer runs, there is an optimal setting for gasoline and it's a good idea to get the carb to that point and leave it alone. Gasoline doesn't need the kind of fiddling we all did on our glow engines. I think I said it earlier....let the spark plug tell you if you are running at the optimal mixture. Sure the engine can run a bit richer but carbon builds rather quickly when that's done.
Hey Matt,
I never had the need to fiddle with glow
