I read these informative message boards and notice ever once in awhile, someone comes along and bashes Champion on their plugs. There are no specifics as to why they are bad. I run Champion plugs in all my pulling tractors as well as my work tractors and have had no problems related to missing, fouling, and other ailments that seem to plauge other folks. What gives with Champions? They have been around longer than most of us.

We have a 1935 Dodge boat currently using a J7. We have been told theose plugs are no longer available....is that true? If so what would you recommend?

Guess I'll jump in on this one. I had brand new Champions installed on my Oliver 77RC. Read a post about the Champions being no good. Bought a set of AC Delcos. Compared the two. Found the center electrode on the AC is more than twice the diameter of the one on the Champion. For a 6 volt tractor, I believe the AC would work better. I figure the larger diameter carries a hotter(or bigger) spark. Try a 4 gauge battery cable against a 00 gauge cable on a 6 volt starter. You'll see what I mean. But I've been wrong before. It's just my opinion.

The larger diameter electrode of the AC plugs is a result of a plug designed for a different heat range. The smaller the electrode, the higher it's temperature will be when it is put under a load in a running engine. If a spark plug with a large diameter electrode is used in an engine that see's little or no hard use, it will not reach it's intended temperature range and therefore it can and will begin to build up deposits which would otherwise be burned off. This will lead to fouling and missing.
On the other hand, if a smaller diameter electrode is used in continuos hard loads the resulting heat buildup with burn the plug. This can also lead to secondary damage as a result of preignition or detonation. The most noticable effect of this is burned pistons. The problem is not necassarily in the plugs but in the formulation of the gasoline and the amount of use the engine sees. Light loads or little use with quickly foul "cold" plugs and hard, long use with burn "hot" plugs. Champion has dropped from production several plug designs and substituted others in there place. Often the recommended plug is not the best for the particular use a person might have in mind.
The old adage still applies: "Hot plugs for cold engine and cold plugs for a hot engine". Regardless of brand name.
My humble opion.

Doug, Like a lot of other guys, I've used Champions for years, but in the last few years I've had more Champs go bad than ever before,also local mechanic is leary about them anymore, so I am getting away from them. If anyone wants to see an article about Champion plugs, E-mail me & I'll send it back....Roger

I OWN A FORD 9N TRACTOR AND AM HAVING A PROBLEM WITH MY SPARK PLUGS FOULING OUT. I WAS INFORMED TO USE A HOTTER PLUG. THE PLUG CURRENTLY IN THE TRACTOR ARE CHAMPION 844-1 PLUGS. FIRST IS THIS THE CORRECT PLUG FOR THE TRACTOR, IF SO WHAT WOULD BE THE NUMBER OF A HOTTER PLUG?

I've Used Champion plugs exclusively in everything that has plugs.... Tractors, Forklifts, Aircooled engines, trucks,compressors, etc. I have yet to experience anything close to premature failure. This is over a 30 year career as a general mechanic. The F11Y champions in my personal truck were installed in 1991, still runs perfectly..... DC Dale

Just because there's so much snow out here I'll throw my two cents in (it probably ain't worth the two cents). I keep a set of Champions and either Autolite or AC's in my possession at all times. I've had tractors that would run great on Champions that ran terrible on the others and vice-versa. I've had the most consistent good results with AC's and the poorest with Champions. Someone should forward all of these messages to Champion, maybe they would improve their plugs.

I'd jump in and tell of my many bad experiences with Champion plugs but they aren't worth it.

Doug, I appreciate your question and I do not have any godd engineering explanation like I sometimes have. Just strictly from experience, it seems like Champions are more prone to wet fouling and foul out sooner in oil burners than the same supposed heat range of Autolites????? Once a Champion wet fouls out, it seems like they are ruined ?? Maybe Autolite heat ranges are a little higher, but if so, one could just use a hotter champion. I think theres more of a problem in oil burners or over rich runners than in good engines. John T

Champion plugs are all we have ever used in our 1946 Farmall M since my dad got the tractor 20 years ago. Since he sold the farm 2 years ago I put the tractor in my garage and changed the plugs and only used it for plowing snow the first year and last year took in 8 antique tractor pulls running 2 classes at each pull. Now plowing snow again with same 2 year old plugs, tractor starting in cold and still running great. Engine was rebuilt 20yr. ago before tractor was bought.
I think Champion plugs have been getting a bad rap the old M has never ran out of power in 2 years now, either pulling a transfer sled in 2'nd gear and spinning out or pushing snow, and even pulling a neighbours tandem 14 ft. disks one afternoon when I was trying tractor out before going to pulls, not yet anyways. Champion seem like good plugs to me, better than what I have seen on the posts in last couple of months anyways.

Some report short life, failure to fire in an engine running rich, tendency to fowl from carbon and reluctance to clean... Not a problem when you install a new set each pull.

I've discovered reading the fine print in the champion catalog that plugs for older tractors have an added series gap to "improve firing in oil." My engine isn't burning oil, so I don't need that feature and am using other brands.

A plug modified to some condition I don't have isn't a plug I care to use.

The series gap probably improves firing--period. It's an old trick to put on a "jump spark" by separating the plug wire terminal from the plug terminal on cylinders that are prone to "skip". There was a spark plug manufacturer, "Aldor", I believe, who sold a plug with such a gap. I'm guessing that, over the years, a lot of tractors (and cars and trucks) burned after catching fire from leaking gasoline on a jump spark. One of my father's tractors did.

Moral of story: It's probably not a bad idea if the gap is internal to the plug so as not to cause fire.

For those who care to know, Aldor plugs with the internal series gap are still available from JC Whitney. I use them on my MF65 and have had good results. I haven't had any skipping cylinders (something the tractor did with Champion, AC, and Autolite plugs). I'm currently installing electronic ignition and a new carburetor, which should have the ol' 65 purring along to the year 2059.

But I do not install a new set after each pull.
