Anybody try and run these plugs all the talk about champion and autolites got me wondering, thinking about taking the champions out and trying these wasted more than 7 dollars trying other stuff
 
Well it all depends on your set up, which we don't know. You just need to figure out what heat range you need then go from there. The NGK is the plug you want no matter what the heat range. I couldn't keep a set of plugs in mine more than one event, sometimes I'd have to change before the next class, switched to NGK and they would last a whole season.
 
Just got done putting them in it fired up quicker the champion d16 were pretty black though we will see what happens on the track in springfield
 
My Farmall had autolites in it for the first three years and ran fine. The only reason I put different plugs in was when my carbuerator got an adjustment done to at a big pull. Jim Benjamin gave me a set of plugs and I changed them in the dark and it still ran bad until I discovered what had happened. If you have your tractor running good I dont think Spark plugs are the problem. I had oveer 110 hooks and never had to check the plugs.
 
She runs good haven"t messed with it for awhile besides changing oil the way everyone was talking I had junk in the poor thing figured for 7 bucks I could try something the experts are using
 
Let me tell you a story about Champion plugs and the H260 Continental:

1985: Built my first H260 engine(stock rebuild) and put a good 4 hours on the engine (and the D16 champion plugs) before the first pull. On the 2nd hook, I fouled 2 of the 4 plugs at the 75ft mark. Took it home and pulled those things out and installed AC C86 plugs. Ran those AC plugs for 4 years until I tore the engine down to modify.

Now I have heard people say that the D16 plug is too cold for pulling. I have also learned in the meantime that the way Champion "rates" their heat range versus everyone else is a little off. Much like a D21 Champion is the actual equivalent of an AC C86 (not the C88).

Fast forward 26 years (2011), I purchased a set of D21 Champion plugs thinking that SURELY CHAMPION HAS SOLVED ANY PROBLEMS THEY MAY HAVE HAD IN 25+ YEARS!!!!! Installed these plugs in a 500+ cubic inch engine, took it to the dyno to tune it, and fouled out 2 of the 4 plugs within a few minutes of dyno work. Removed those POS and installed Autolite 386 plugs and am still running them today.

Some people may say that spark plugs are like oil, but you could not give me a set of Champion plugs and/or give me enough money to install them in a Massey 44.

It feels sleazy putting jap plugs in old usa iron but if you try em you wont go back. Nothing beats up a plug more than a two stroke engine and these njk's are mfg recomended in them for a reason
 
I can tell you from working on motorcycles my entire life...There is no plug made(for the money)better than NGK...I use them in everything I own including my pulling tractors...Champions make great sounders for Ice fishing! and yes AB6 is what you want to use,They were used in old 2 stroke snowmobiles...As far as being made in Japan..YUP they are,Just like the electronics in most pick ups,cars,and Harley Davidsons.
