starter problems

[linski]

I did a search, and couldn't come up with anything. I got a 1983 300d turbo. The starter, every now and then sounds and acts like its free spinning. I put a rebuilt one in and it does the same thing. It will free spin ounce or maybe three times, then start right up. I took that first starter down to the local pro, and he said theres was nothing wrong with it. It looked good and it bench tested out fine. So, has anybody else has this problem ? Did I just get 2 ****ty rebuilt starters ? Or am I looking at something ? Thanks.
