CC,
You probably need to replace the governor weights and pins. Very little slop in the weight pin hole will cause a sluggish governor. If a weight is broken, be sure to find all of the parts. Broken pieces have a habit of hiding on a ledge behind the cam gear and can cause MAJOR damage when they go through the gears. Leave the distributer in the governor housing. Before you remove the governor housing, mark the exact position of the rotor in the distributer, then when you reinstall the governor housing, you can mesh the governor gear so the rotor is in the same place. Then a recheck of the timing is just a matter of hooking up the timing light. That is IF you didn't turn the engine when it was apart! Duey
