I lifted this from an old post. It works. The white wire will be your "kill wire". The new coil will have only 1 terminal on it.
The plug wire is just long enough to work. You'll want to take a piece of 1/4" fuel line and split it. Put it over the tin to protect the plug wire.

This is the coil that I used. Less than $30.
Kohler P/N 20 584 03-S.
It fits a 20hp Kohler Courage.
I bought my coil off of Amazon.
