Thanks for the info.

The engine is NIB other than he took the carb for his .61 (I think) after he glitched and augered straight in. I suppose the other carb was a disaster after that. [:@]

On the topic, when you say the barrel set screw, do you mean the screw that sets the carburetor in the throat of the engine or the "barrel" of the throttle? If so, should you lock-tite that screw? I've never done that on my car engines, but maybe it's a good practice?
