When I was a kid I used to do our next-door neighbor's driveway with their snowblower and it had one of those.
I asked here and a few people knew of that setup, but there's very little info about it on the web. I've spent a fair amount of time searching but could never find any docs or photos.
I wonder if that was the first Tecumseh electric starter?
