Oh, that's a good point, I didn't think about the easy spin start. Is that something that's centrifugal and stops once the engine starts? If that's the case, I wonder if it's sticking or otherwise not operating.
If it was a cam problem, I don't think it would be caused by wear. It would almost have to be a manufacturer defect. The lobes have plenty of lift, more than my dial indicator can measure. A worn cam wouldn't have a high spot on the bottom of the lobe.
