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
