I'm looking to start ordering engine parts for a late 60's, 3.5HP Tecumseh engine that came stock on a Sears minibike. The model/sn plate on the blower case is long gone, but I do know that it is a 3.5HP. Can I just assume that it's a H35 model or that H35 model parts will be compatible? I'm not at all familiar with the differences between the early and late model Tecumseh 3.5hp engines so any advice will be greatly appreciated.
Here are a couple pictures of the engine...if that helps at all.
