What plugs do you all run in your Johnny poppers? I was under the impression that autolite 3116 was the plug to recommend but they wanted to sell me champions at the Deere dealer. Plugs will be living in a 1954 70.

Just go to "AutoZone" and buy them..!!
Autolite #3116

Champeens are JUNK..(even IF you get 2 GOOD ones).!

That's just what I thought, I just needed to hear it from someone else I guess. Bought another 70 today at a sale, it was only hitting on one cylinder. Goin back out there to pick it up tomorrow and figured I'd hit autozon on the way and stick some plugs in her before I load her up. Now have a 53 and a 54'' now need a 55 and a 56. It seems early number series and styled A's and B's are the only two poppers I can afford.

I agree with Ron... Champions ARE junk... I ran two B's with 4 row cultivators on peanuts down here in Va ever summer for 30 years and Champion D23, which is the hottest plug they make, fouled out 5 times worse than either AC or Autolite. Tell the dude at the parts counter "No Thanks"

Gave 2 for this one, I have another in about the same shape that I believe is low houred that I gave 2250 for, both needed tires at the time of purchase. I'm not sure why they don't bring more but I enjoy em and they are in my price range. I saw a '49 g with a wide front and perfect paint/metal bring dam near 8 grand today.

I've been using AC C88L plugs in my B and 70 and have no complaints.

I use the Autolite 388, but am told on here that the autolite 3116 is hotter and better...

Dad's old A ran on Champions for years. Changed to Autolites and it ran like crap. Cleaned up the old champions, gapped, and it runs like a dream. These plugs are at least 20 years old.

We use Autolite 3116 spark plugs in our Model 70s.

Actually the difference is the 3116 is a non resistor plug unlike the conventional 386 and slightly hotter 388. I believe the heat range of the 3116 is right in close to the 386 and 388.

In the later styled tractors that used an 18mm plug, I believe Autolite 386 was close to the factory original heat range, while 388 is a bit hotter. Unlike the 386 and 388, the 3116 is NON Resistor Plug which is better matched and best for use especially if you have a Magneto Ignition although sure it works fine in a coil distributor ignition as its close in the heat range of the 386 or 388 family.

My D-21 Champions have decades on them too, so I don't usually buy spark plugs, but did break down last week and get four replacements just in case they too go obsolete in the next 60 years or so. $2 each.

Unless you listening to AM broadcast radio, conversing with the airport control tower or working an AM Ham Radio Band? Radio suppression resistor plugs are not required .
