Tecumseh lighting coil ??

Basically the deluxe models from Rupp, Mtd, Fox etc. Of course any model that came with lights etc would most likely have them, except for the ones that came with a separate battery powered system, if the engine hasn’t been swapped out. The ones that do usually have 3 wire T shaped connectors hanging out the front side of the tecumseh engines. If they don’t test out hopefully all the correct parts are there and can be made right. The correct flywheels etc are hard to find and are not cheap. Good luck in your search.
P.S. I don’t know about the system that Briggs and Stratton uses.
