Kohler M20 spark plug and gap?

Recommended Posts

The Simplicity owner's manual shows a RV 15 YC with .025" gap, The Kohler M20 owners manual shows a RV 17 YC with a .035" gap. I'm going to put new plugs in, which should I use or is it a combination of the above.

I would pull a plug from engine and replace with whats in it or go by the Kohler owners manual. I have seen Simplicity manuals in the past with misprints. Kohler should know since they made the motor. Kohler Spark Plug Conversion Chart http://www.asecc.com/data/kohlerplug.html

      Site programming updates were made 3/23/2024. As a result some things have changed including dues payment options. We will continue maintenance and work with technicians to regain credit card payment option and clear up minor challenges. On positive it appears attaching pictures is now easier. Good day. Gene
