wiscootsin is not full of cheese on that. An auto battery should spin that starter over like it has double or treble the normal power. Makes me question the starter motor condition. Could have a buncha goo inside, or the brushes need to be cleaned a bit, or the commutator(armature) is gunked up. All three will tend to limit starter operation and thus how fast(if at all) it will spin the crankshaft. If you remove the CVT cover and the Bendix(you can snake it out and in with some wiggling), and then engage the starter motor with or without a jump, the armature should spin freely and fast. If not, either you have a bad ground, bad connections, bad terminals, or bad wire. Or a gunked starter. If/when you do disassemble the starter, keep track of how you put the brush carrier back in place. It will rotate the wrong way if you cross things. Clean the commutator, the ends of the armature, and use some brake clean on the bushings at either end. I used a dab, only, of grease into the bushings when putting back together. Trying to remember how I kept the brushes retracted ... so far to no avail. I think string or thread could be used, perhaps toothpicks? It's been a while. tom

I gather It wouldn't disengage until it started turning at high speed. Lucky I had a spare
