    I suspect it is time for an evaluation of the engine. The big ol’ cans of a 1970 40 make it so they are unlikely to stall, even on one cylinder. Do a compression check, tune up and try again…May be as simple as a carb adjustment. But 650-700 RPM sounds like a reasonable number to shoot for. I’m not sure your question has an answer that is in print; but if anybody knows, it will be these guys.

    Long live American manufacturing!
