Small Engine Troubleshooting Problems? Ask a Mechanic Now.
What is the engine model number? CV, SV. etc? I see no one wants to tackle this!
See section 8 in the manual link above. See if you can identify your ignition type, Koher uses three different types! Can be identified by the number of small wires on the ignition modules.
You will want to eliminate the fuel solenoid in the Kohler carburetor. That will get rid of one wire!
I see question is still open, have you had time to check the wires?
