Not a lawn mower but a snow thrower. It is a White Outdoor Products with a 10 hp Tecumseh engine. It has an electric start which uses 120 vac plus the manual start. When I tried it the electric starter this morning the starter just made the grinding sound not engaging the fly wheel. I disassembled it and lubed the starter drive, but the same results. Is this a replace the starter or is there some repair that can be done on the unit?
