Recently purchased a Tilton reverse mount starter, and it doesn't engage the flexplate everytime. It will start the motor a few times with no problems, and then 3 or 4 times in a row it will just hit against the flexplate and not mesh.

We noticed our bellhousing has two sets of holes, but that didn't seem to help. When we grab the starter drive, it does feel extremely loose. How much freeplay should this have, or is that our problem?

Any ideas or experiences are welcome, as I plan to run this weekend. The whole setup is a Tilton Reverse Mount Bell housing w/ starter and 102T flexplate setup.

Thanks.

I have gone through that same deal. And know others that have had it too. The basic problem is lack of clearance for the starter gear to engage. You need about .030" between the bottom of the teeth, use a piece of welding wire (.035"). I'm certain you will find that it will slide in, in some places, but not others. You'll have to rotate the engine 360 deg and check it all the way around. Because these flex plates are out of round. Its a pain in the **** to do. However if you do spend the time and do it right, it will start every time.

Thanks Gene.

For the spots on the flexplate that don't have the proper clearance, what are you doing so it does?

Can you explain further on, "spend the time and doing it right, it will start everytime".

Thanks again.

Rotate the engine 360deg. all the while checking the starter gear mesh. Turn the flywheel 1",pull the starter gear out and measure. Mark the flywheel and rotate it 1" again, check and mark the mesh. After you have done the complete flywheel, you'll notice a pattern. Shim the starter for the best average overall clearance (.030"). The areas where there is no clearance is where the starter will not engage the flywheel to crank the engine. Take a file and carefully remove enough material from the bottom of the flywheel teeth for the starter gear to slide in and mesh.
I bought expensive flex plates that are suppoed to run true, but after a while they warp also. Thats because there is no toqure converter to keep them straight. Use care when you tighten the crank bolts also,pull them in even, not cranking 1 in then the next one.
