Re: Starter noise on 258-6 cyl
I have heard of shimming the starter on an AMC 6, but only on my buddy's old Rambler. [img]/wwwthreads_images/icons/crazy.gif[/img]
Any chance that your ring gear or flexplate is on backwards? I don't recall if the ring gear is symmetric to the flexplate - mounting it one way or the other (if that's even possible) could put the ring gear further away from the starter.
I suspect your problem is more in the starter itself. The 87+ YJ used a mitsubishi starter, and it ain't cheap. [img]/wwwthreads_images/icons/tongue.gif[/img] I've replaced mine, so I know. When mud and goop and crap and other swamp-type goodies enter your starter, they totally play havoc with all of the seriously heavy-duty plastic parts [img]/wwwthreads_images/icons/crazy.gif[/img] That's been the problem with mine and guys I wheel with anyway, and we've had to take 'em apart and clean 'em out to get 'em to work again. You say you're on your second one though, so that's probably not it.
My guess is that the starter IS energizing enough to make the switch to let it turn over, but it IS NOT energizing enough axially (in the direction of the flywheel). I would take the starter out, clamp it in a vise, and actuate it with a battery and some jumper cables, and see if it energizes all the way when the gear pops out. BE CAREFUL. If it does, it's a block/ring gear/flexplate issue. If it don't, it's a starter issue. The linkages and stuff inside the starter that energize the gear are all plastic - it's pretty scary.

Maybe you got a bad rebuild house and they made some errors.
I've even had starter problems because my motor was a grease-ball (before I rebuilt it, it leaked a lot of oil out the breather at the top due to blow-by). The oil would leak down the side of the block, and onto the starter. This wasn't a problem until winter came, when the oil in the starter got cold, and the starter wouldn't turn. [img]/wwwthreads_images/icons/crazy.gif[/img] Of course, things only don't start when it gets cold [img]/wwwthreads_images/icons/tongue.gif[/img][img]/wwwthreads_images/icons/crazy.gif[/img] and you have to lay on the ground to remove the starter.
Just my opinion. Dave's tolerance issue could still be the thing too, but did it always do this? If not, then something has changed.
