Yeah actually it wouldn't be too bad.. I think I would fabricate some kind of (throttle hooks to the governor) set up though.. I just wired right to the throttle plate so I could go wide open..
It's a two stroke.. :shrug:
But they do have a wind vane governor about like a briggs 3 horse.. I think I would attach to that some how, so you can keep the RPM's down to a dull roar for little kids..
A jack shaft is gonna be about crucial too... SOME KIND of gear reduction.. They aren't much for torque but they get going pretty good.. They make power at wide open.. :doah:
I think I would aim for 25 miles per hour, at 6,000 RPM's.. Then govern the engine to like 4,000.. Something in that ball park.. That way you have the power to go without issue, but don't burn the engine up rinning it's guts out..
I've got one with a weed whacker engine that pulls me but is only about 7 miles per hour screaming it's guts out.. :laugh:
