Thanks, Curt.
I read someplace here on the forum where a builder cut down the fins and then with the engine running used a flat file to dress it up. Even so, I think I'll check it for balance just for peace of mind. Then forget about it.
It's funny how I never really considered a Tecumseh for a build. Seemed like everybody was using a Briggs & Stratton if going for an old American made flathead. Mr. B. was an exception with his fine old Wisconsin, but those are hard to come by. These Tecumsehs are common enough in my neck of the woods and for this build it has worked out very nicely. It fits into the Schwinn cantilever frame well and with the electronics being under the flywheel a seven inch pan makes an easy flywheel cover. If someone offered to swap a 5 horse Briggs for my Tecumseh I'd say no thanks, happy with what I've got. I'm sure it will have plenty of grunt and top end for my needs even if the build eventually becomes a "Sociable". And I have a second Tecumseh just like the one I'm using thanks to you, sir. Nice to know there is a spare sitting on the shelf in case I need it. Or if I hand down this bike to one of my sons someday it will come with a spare engine.
Enjoy your holiday, my friend. And have fun tinkering out in your shop. It is insulated now if I remember right. Lucky you to have a good workshop!
