Has anyone ever done this? I purchased a toro 223D from a newly widowed woman. Her husband had swapped the Kubota diesel for a 3 cylinder gas engine out of a geo metro. The engine had a throttle body which he removed and retro fit with a carburetor. The thing I can’t figure out is the ignition. It looks like he was going to use an old coil from another tractor based on the box of parts she said we’re his ‘mower pieces.’ I’m a self taught lousy mechanic and the electrical stuff is where I really fall flat lol. Anyone got any ideas on how this could be done?
