I want to put an electric assist on my ride. Anyone have any luck with a mid drive? Ideally I would like to jerry rig my own mid drive hooked up to the engine chain. I have some ideas for either a 12v starter motor, or some other 24v motor similar to the Bafang shape. Has anyone done this?

Starter motors will overheat if you operate them very long. The successful gas/electric hybrid bikes I have seen had an electric hub motor on the front wheel. If your motor chain breaks, the electric hub motor will still power you home.

Yes I tried with a 250 Watt Scooter Motor but I quickly found out that it needs to be a geared motor to develop the required torque to turn that back wheel.
