Kelsey 91 #1 Posted April 10, 2022 Greetings, I stopped in at Advanced Auto for a NGK B-LM spark plug and I bought a NGK B-2. Can the Latter be used in place of the original plug? What is the difference between the two? The newer one is a bout 1/2" taller. Thanks, Kelsey Share this post Link to post Share on other sites

Kelsey 91 #5 Posted April 12, 2022 Thanks Mike! The old plug was in my son's magnum 10HP. Advanced Auto salesman couldn't elaborate on the new plug. Curiosity got the best of me to ask, internet wasn't all that helpful except for a few things. Share this post Link to post Share on other sites
peter lena 9,088 #6 Posted April 12, 2022 @Kelsey spark plugs are run , by related wiring , make sure every connection is solid , typically add light swipe of dielectric grease , inside of the spark plug boot , makes installation smooth and ensures conductivity . look over each wire run , just a suggestion , pete Share this post Link to post Share on other sites

Just so the WH forum knows, I changed out the plug, air filter, fuel filter and used fresh non-ethanol gasoline in my boy's wheel horse. She did a heck of a job for the first mowing of the season. Sure beats a herd of goats. 1 Share this post Link to post Share on other sites
