My friend and I have been converting a few motors, with a HUGE thanks to the info here, and you guys ! And we ran into something new . We got a hold of a 46cc poulan that seemed to be seized ..but after opening it up is seems there is a cage the rear bearing that came apart. I didn't get to see it opened , but I am sure thats what my friend told me. Has onyone else run across this? Is this a weak spot of the motor? Or did we just get an odd problem with this one?

Now that I think of it he did mention there was a slight scoring to the ring and piston, but it doesn't look like it had a major problem do to lack of oil ..and freezing up violently...

Also there are both 2 magnet, and 3 magnet flwheels on this motor.. can anyone tell me the advantages to one over the other?

Thanks guys !
