Chainsaw Repair

I understand what you are saying about the shop guy trying to sell me a new chainsaw but I know him pretty well and not positive he has that angle but I could be wrong.

So with what you know what could be causing the hard turn? In other words with the flywheel removed turning it, it has spots where it is hard to turn then gets easy and then real hard again.  My limited knowledge I know that during compression stroke that it is hard to turn but this is not that at all.  Could the bearings be out? Crank bent?
