Kohler command ch16s single ignition
 

Lt2138 with CH16s engine
I bought the mower from an indivual
I found there was no ignition coil and it looks like there had been a dsai or other module on the outside of the shroud, I'm not quite sure
I have searched everything I can find on this engine
Obviously I want a MDI ignition, but which one
When I think I found one on line I notice 2 prongs instead of one,
I'm thinking those are for twin Kohlers
When I checked youtube, all of the videos were for twin cylinders just like when I google ignition coils
I've only found 1 that might make me happy, 25 584 15s.
Only one I found with only 1 prong for kill switch but I don't want to spend upwards of $60. then find it doesn't fit

ANY INPUT IS APPRECIATED

Taco, click on the "Cub Cadets parts and service" up above and enter your info. It looks like there is a module that goes to your machine but I don't know what all is missing on yours because i don't know what you have.
Good luck and keep us posted.

See if this video is any help.

I've had that ignition system on a few vertical engines but not horizontal.
