I have a horizontal shaft Tecumseh im tryin to find a model# for, but engine is missing the flywheel/blower shroud, where the info is supposed to be. theres some other numbers stamped into the case opposite the flywheel side, but I cant find anything online( yet) to help me identify what I have. any help on how to find out? lookin for parts, I don't think Tecumseh horizontal shaft w/ electric start is a good enough description.
