The engine should be stamped with a model number. Do you find any numbers on the engine itself? Kubota made at least 7differentt 2 cylinder engines that could have been used. With model number, we made be able to determine the starter and drive.

No numbers on the engine. May have been on a plate that has long gone !

I doubt this is it. I will opt out, and see if anyone else can help, sorry. Kubota engine should have a machined pad on the engine block, where a series of numbers would be stamped. Model and s/n would be there.
