I have this engine and am getting ready to run it. Can't find my instructions anywhere but I'm not doing anything with it until I find them. I do remember they said to use nothing but a castor oil/gasoline mix.
Something I've noticed about the carb that concerns me is that the carb can't close all the way. If I back out the throttle stop screw just a little bit then the carb barrel can spin around. There is no in between setting where I can close the carb all the way.
I assume that means that the engine will quit with the carb still partially open.
Unless I find something that states otherwise I am planning on using methanol-free gasoline. Is that a bad idea or should I use just regular pump gas?
