Maybe swap leading and trailing as an experiment?
If the voltage at the coils is too low due to the I*R drop during start you won't have a strong spark. Add slight compression loss and a weakened battery and a slower starter and you're not going to start. But I'm just pulling ideas out of my *** at this point...

Working well at 14V is different than maybe less than 10V? Do you own a meter?

Startermotor was fubar . Took it apart and found two of the brushes were worn way more than the other two . so I stretched the springs on the two short ones and voila !!!!
Still will need a new starter motor though because this fix will be very temporary .

Ha, that's pretty brilliant actually. Not being very mechanically minded I wouldn't have thought of that. When I get mine replaced I think I'll ask to keep my old one so I can tear it apart.

Interesting find Brettus.
Though I'm curious... do you have the original, updated, or upgraded starter?
When my original crapped-out on me, I thought the same thing... worn brushes.
Thought I could just replace the worn item instead of purchasing a whole new starter (this was before I knew the updated/upgraded starters utilized a larger motor).
But everything I measured (brush length, commutator diameter, armature, pinion gap, etc) where all within spec.
I noticed the brushes were all resting against the commutator, so there was no gap.
And the brush length was 0.47" (standard it 0.48" and minimum is 0.28" for original MT version).
If it was the brushes, I was going to purchases new ones at McMaster Carr and solder them to the copper wires.
Can you tell me what the brush length is on the worn ones you saw?

The copper wire was pretty much bottoming out on the side of the plastic carrier . Length maybe 7mm ..... ish on 2 of the brushes . More on the other 2 .
