Stealth126 54 #1 Posted May 22, 2018 Replacing my spark plug, but the K241 manual has 3 different gap specifications: Battery/Breakerless .035 Magneto .025 Gaseous fuel engine .018 I don't know which applies to me. It is on a 1067 and has a starter/generator. Share this post Link to post Share on other sites
Stealth126 54 #2 Posted May 22, 2018 Also, spark plug recommended is RH10C which is a resistor. Should I just go out and buy it or are there any thoughts about better replacements? Share this post Link to post Share on other sites

It is on a 1067 You have a "Battery" ignition system and the plug gap should be .035". I too use Champion H-10 C plugs. 2 Share this post Link to post Share on other sites

Stealth126 54 #6 Posted April 16, 2019 I have kept it gapped at .035 and runs great. Both Kohler manual and service manual specify .035. I also have a John Deere 110 and the John Deere service manual for my serial number with a K241AS says gap the spark plug at .020 for battery ignition. I didn't believe it so I double checked that I was reading right and that it was referring to my engine. It very clearly states .020. Can somebody with more understanding than I have explain to me how 2 battery ignition K241s need to be gapped differently? Share this post Link to post Share on other sites
Stealth126 54 #7 Posted April 16, 2019 Both manuals call for Champuon H-10. Both call for .020 points gap. Both call for .009 and .018 intake and exhaust. Is it just wrong? Share this post Link to post Share on other sites
Stealth126 54 #8 Posted April 16, 2019 Scratch that. John Deere manual calls for .010 intake and .020 exhaust. So what is this some setup that John Deere thinks gets extra performance out of this engine? Share this post Link to post Share on other sites
