Got another one today,as if I needed another project. This one will have to wait til spring,but I wanted to start the thread now with pics of as recieved condition. Need an ID on the motor. It has a Sears # 143-615062. It's a 5, 6, or 7hp Tecumseh, but I don't know which. Bike seems to be 100% original and complete. Scrub brake and small jackshaft brake both still work. Throttle still works, etc. But with the build off and the Boonie ahead of it, it will have to wait, but I'd still like to ID the engine, so I can start getting the parts to rebuild it and the carb.
