Hey Hoyt,
Thanks a lot for helping ID my motor. Yep, the III may indeed be a 111. I thought a series of letters instead of #'s and letters was weird, although I swear the things look like I's.
I'll try taking off the starter to get at the casting code behind it. Bought this motor at a swap meet and I'd just like to find out all I can about it.
Many thanks!
Chuck
