changed the brush set on the 2-speed type?</P>

had the same problem on two separate motors - when the motor casing is tightened
up to the gearbox casing the armature binds very badly, I've had to put a small
washer in one particular place to angle the two casings slightly.</P>

the second one I even refitted the old brush set and it ran just fine (the
brushes ARE well worn and the motor has become very reluctant to get going after
not being used for some time), but with the new one refitted it was binding
again.</P>

comparing the old and new brush sets although there is obviously significantly
more carbon on the new compared to the old, the springs don't push the backs of
the brushes to anywhere near the position of the old brushes, which means that
although the business end of the new brushes do stick out further than the old
brushes, it is only just further, so they won't wear very much at all before
they fail to make contact.</P>
