I have a 4231 with an intermittent no start condition. Traced power to the starter without issue so I replaced it. Also using a brand new battery I got from a friend. Still intermittent won’t crank. Relays click and fuses have been replaced.

Any ideas? Neutral switch has some play so I put a spacer in there, no change. Not a whole lot left to look at. Ignition switch maybe?

Intermittent is tough to diag unfortunately

Update: the armiture is striking the flywheel. Doesn’t look like any birds on the flywheel but that is the issue. I may file it a bit or see if I can tweak the starter away from the flywheel. See if I can gain a few thousandths. Hopefully that and some grease will take care of it

Make sure you a good ground.
Got it sorted. Wasn't the ground. For some weird reason it didn't line up. No burr on the flywheel. I took it off and reseated it with a small tweak away from the motor and it works fine everytime. Replaced a lot of starters, never seen this before. Thanks
