I have a rupp TEC hs40 slanted intake for sale 50.00 shipped.

Currently building up HS40's and wanted to note a change that Tecumseh made regarding pistons and rings. In later years Tecumseh started using thinner rings. The piston size on an HS crossed with some of the OHH engines (as does alot of other internals) so they offered that piston/rings as an...

I bought a 81 Sears Green Streak from a swap meet to build to a customers specs. The bike came with the original Tecumseh 4hp HS40 on it. It had spark and compression and would run if some gas was dribbled in the cylinder but the carb wouldn't let fuel in. I installed a diaphragm carb from a...
