Re: Starter...again...still..

I would go the high torque mini starter route, others may disagree.
I would add that your prob doe's sound like it's to do with the meshing of the starter gear and the teeth on the flex plate and that it needs shimming, gear mesh can be measured using a paper clip, open one up and if you can pull the small gear on the starter out by hand till it engages or meshes with the teeth on the flexplate then see if you can pass the paper clip between them both, (that's the valley between two teeth on the FP and the high point of a tooth on the starter gear. If not, it's to close, and if you could pass something more akin to a BBQ skewer or 1/8 drill bit between them then it's to far apart.

To close


To far apart


This pic shows the correct distance while in resting position. Set too far back from or to close to the FP and it won't engage correctly.



Pics of my old starter & FP show the kind of damage that can occur when they don't engage properly





Hope all this is of some use to you.
