marreque 213 #1 Posted May 27 Looking to see if anyone has an answer, my k241 has shorted out 2 spark plugs in the last year. Anyone else have this issue?? Share this post Link to post Share on other sites
WHX?? 48,814 #2 Posted May 27 I guess I never heard of a plug shorting out. Fouling out yes. A pic of the plug will tell us how the motor is burning fuel. Proper plug? Should be a H-10 champion or equal. Not overheating cooling fins clean? 1 Share this post Link to post Share on other sites

953 nut 55,188 #4 Posted May 27 Check the gap of your ignition points, it should be 0.020" If the gap is not correct yout ignition timing will be off and may result in poor performance and carbon build-up. 1 Share this post Link to post Share on other sites
marreque 213 #5 Posted May 27 (edited) Not fouled but complete loss of spark at the plug. Second H10 in 6 months. Change the plug and spark is restored. The first plug was probably 30yrs old and I understand that, but the second is a few months. I’ll post a picture of the plug later.

Its original engine and carburetor and really haven’t been touched. Amazing how it still runs as good as it does 59yrs old 4 Share this post Link to post Share on other sites

Handy Don 12,212 #8 Posted May 27 A puff of black smoke at start could be from choking. More and the mixture is too rich. Blue/white smoke is burning oil--not conducive to long plug life. A mismatched plug could be in the wrong heat range and would work poorly or fail after working for a while. 1 Share this post Link to post Share on other sites
