Jason, It may not still be getting enough fuel either? Make sure it has the governor spring on throttle rod and lever. It's just a simple flyweight type governor and sleeve and lever on end of camshaft. Engine speeds are changed by using different springs and in different holes. You can adjust the throttle rod where it just enters the governor lever hole when governor weights are "in" and carburetor throttle is wide open. Something else I learned on the Wisconsins is the valves have to be right. Can't be grinding a lot off them or seats or they won't work. Seats are replaceable and you will need to replace the valves with new ones if worn much. I have never had problems timing these one cylinders? Just put the mag on aligning marks and go. I&T manual says set timing same as for battery dist. at 28 deg. BTDC. The holes in mag don't allow for any real timing change on these? It just says if timed correct the mag should trip when flywheel keyway is up. Crankshaft and camshaft endplay should be kept in tolerances also and not too tight on these engines.
