I recently found a free tiller with the numbers 333d-th 1002. It has the date 10\25\79.I need a flywheel but don,t know what or where to find one. Don't really know what model and serial numbers this horse has. I can't find any numbers on the kohler engine.I looked the shroud over with a fine tooth comb. Figured they were on a decal that is now missing.
