Exactly, you need some sort of external return spring. Rig one up and test again. With your linkage closed by hand (fighting the slight accelerator tension) its still revving up?
Not sure I am being clear, or maybe I am missing something. I am manually operating the throttle, by hand, and the engine is running away. Weirdest thing...
We'll test again tonight, and yes, I'll rig a return spring cuz it's just a good idea :) and see how it goes. But like I said, with me operating the carb by hand, it goes into runaway almost immediately.
