Flathead Starter problem

Hi guys I have a problem with my starter ring gear it sounds as if it is creeping back and touching the flywheel ring gear while the engine is running causing a rattle.
I removed the starter and found that the weighted little plate on the back of the gear was lose and that was the high pitch rattle I was hearing.
I change the complete bendix assemble from another starter I had and there still seems to be a rattle when driving but not as high pitched as before I changed it.
It seems to be the starter gear sliding back against the fly wheel.
Question is what stops this from happening?
Thanks in advance

Here's a pic in case there are other styles.

Everything looks correct in the picture. Are you certain the starter mounting plate matches the hogs head?
