So several days ago I bought this mid '70"s ITOM (see pic). It test drove well. Drove it at home just a little in the driveway and it seemed to loose power. It eventually didn't stay running. I bought a new spark plug and starting fluid. I got it running fine on the kickstand (smoky exaust though). When I hop on it cuts out.
Any ideas? By the way, I am totally new to mopeds so I don't know anything about what's what or how to repair it. I am however a fast learner and am willing to do the work.
