When I questioned him on this he said that Kohler had three different flywheels and the difference was the location of the keyway. He sent me a different flywheel but I have never installed it as I learned that if I start it at an idle and do not choke it until it is spinning it will start ok. I have noticed that it seems to have much better throttle response and lugs better than my other CH23 in 1872 #1. Reminds me of advancing the timing on a small block Chevy and having trouble starting it when hot.

the smart spark unit is a ignition delay unit ( which works reverse of its wording ) , at low speeds its about 5* advance and advances the spark slowly till 15* at 3600 . the more advance makes the more top end torque , cleaner emmisions and runs cooler . in theory its supposed to be like a weight advance unit .. kohler has a section on it in some of there manuals . some of the ones I have converted back to standard mag units , we seperate the starter from the ignition , spin the motor over , then turn the ignition on . and the motor fires . I haven't tried to use a offset key like we do with cars yet .
