He did say it's just a simple motor, but something is stuck good inside... I think he said it was the clutch? But at least he's a mechanic, and knows what he's talking about.

I'll consider emailing them the link and filing with ripoff reports.com. Thanks for the suggestions!
I've bought a couple of kits from Zoom and they were fine. One thing they do say is (It's in the instructions) is that the sprocket may not want to turn and you need to use a screwdriver or other prying device to turn it initially. Mine were like that and I panicked on the first one till I tried their method. After a few turns it loosened up and worked great. Might not be what you had but this is from my experience with Zoom. I'd buy from them again.
