TCI chevy trans adapter plate starter probs

I have tried a few differnt starters and all turn the engine a round or so then kick out. I have used tons of these kits and never had one give this problem. Anybody know the fix for this or do I have a 1 off problem? Thanks

I use a chevy adapter and haven't had a problem. Not quite sure what your problem is. If you could explain more it might help.
