(ET) Mower motor stuff

[Chris Zach <czach computer org>]

Since I couldn't get my mower motor flange off, I figured I'd try and 
clean it out. A bit of brake cleaner rinsing got a lot of gunk out of 
the bottom bearing and now it spins more freely.

Problem is this: Still doesn't spin when put together. In fact it feels 
as if the armature is rubbing against the magnets for some reason. There 
is no side-to-side play, it's just rubbing and I think this is part of 
the cause of the extreme friction and the "chug chug" operation under 12 
volts (with insane current draws)

What happened with these motors? They sat all winter; that's the only 
thing I can think of that happened.
