I am looking for information on the 60 hp distributor. I purchased a "37" flatty that has a later model distributor on it. When turning the engine over the distributor shaft moves off center. I removed the distributor & found that the tabs that engage the camshaft are offset. It appears that the groove in the camshaft is not offset causing the distributor shaft to run untrue. Is there a distributor that will work on the 60 hp ? Thanks in advance for the answer to my dilemma.
