Waggles:
Must admit I would replace brushes anyway if you had it apart and clean commutator. If thats all OK and the bearings are OK (not dry or worn allowing the motor to go out of line) then I would check the relay next

K2-K6:
Are either the earth lead or positive lead getting hot during the turn-over? if so they are not passing sufficient current.

Try connecting the extra battery to where the earth meets the engine and positive staright to the starter post (may need two people) to see if it's any better. If it is, then you could have a fault on the wiring or an inconsistent earth.

miclyn:
I have tried all of the suggestions except new brushes. The only thing that gets warm is the starter motor. The brushes were within the tolerence in the manual, there was no burning on the commutator and it did not need under cutting. The only other thing i suppose is the windings in the motor. Just wish i had a spare starter to try before taking the plunge and buying one.
