A friend gave me a cheap impact wrench to see if I could get it working. It's a "Snap Fresh," which he bought from Amazon a while ago, and he got a refund because it didn't work right. It spins fine in forward, but it spins in reverse for about half a second. It seems like there's something mechanical stopping it. I guess there's no harm in taking it apart and looking inside. He doesn't care if I fix it or make it worse. If I do this, I'll post pictures.
If so the reversing switch isn't making good contact, probably sticking until vibrations from running makes it complete the switch process complete.
