Retired Wrencher 4,916 #1 Posted May 13, 2011 I have had some trouble with champion plugs lately I changed everything and it turned out to be the plug I usually run H10c in the old K`s I herd a bout Autolites or NGK`s what would be the cross reference from champions to other brands like above.?????

squonk 39,190 #2 Posted May 13, 2011 Autolite 261 replaces h-10. It's all I use in my Kohlers Share this post Link to post Share on other sites
TT-(Moderator) 1,129 #3 Posted May 13, 2011 Autolite 261 replaces h-10. I'm pretty sure it's just an oops when you typed the number, but it's 216 - not 261 I believe the NGK B4L is also a good substitute. Share this post Link to post Share on other sites

Pollack Pete 2,273 #5 Posted May 13, 2011 does anyone know if there is a difference between Champion H-10 and H-10C ? i have bunch of new H-10 and nothing to use them on I think the C stands for copper core?? Your H10's must be O-L-D plugs.But I'm sure they're the same. Share this post Link to post Share on other sites
JoeMonag 1 #7 Posted May 14, 2011 I had tried the H-10 in my tractors a 310-8 and a 416-8, and went back to usuing the Autolite 216, they seem to run better. BTW my dealer recommends the Autolite 216. Joe in Norton Share this post Link to post Share on other sites
tbbahner 27 #8 Posted May 14, 2011 As soon as I see a Champion plug, it goes in the trash. Too often they "almost fire some of the time" that they make you chase everything other than the obvious, a bad champion plug. Not fond of them at all. Just my 2 cents.

JoeMonag 1 #9 Posted May 14, 2011 I do use champion spark plugs on mine, and my neighbors Sears - Briggs engine riding mowers, and my bro.-in-law's Cub Cadet Kohler command engine. Of course thes are much newer over head valve engines. But as I said in a previous post, the Autolite 216 seems to run better in the flat head series such as the K341 on my 416, and the M-10 on my 310.

qd-16 14 #10 Posted May 14, 2011 I just had to replace a bad champion H-10 in my 310....bad thing is that it took me a very long time to figure out that the plug was my problem all along.......cleaned carb., replaced all fuel line, new points, different coil, tried different muffler. Oh well live and learn.....try the simple things first! :hide: Share this post Link to post Share on other sites
