well the test period is over for the 3112 plugs
and they worked great, not a fouled unit in any of them, they fire quick and from my understanding they are one step hotter than the AL-437 i put these in a 9n that was always going through h-12's they looked like i had bad rings or something wet black oily crud on the plugs.. i pulled the 3112's today and they appear to be ingiting excellent no trace of any oil residue on any of the plugs...
thats pretty impressive

I turned wrench on motorcycles for years. Honda used to ship their 2 cycle dirt bikes with Champion plugs in them for some unknown reason. My experience with setting up brand new dirt bikes was about 50/50. 50% of them wouldn't even start untill I put NGK's in 'em. The other 50% wouldn't make it out the shop door before they fouled, and again I had to put NGK's in 'em before we could sell it to a coustomer.

NGK is a great plug. That's all I run in my 2 strokers and my Cammaro

Re: NGK PLUG ABUSE in reply to HOOKER, 03-10-2005 15:44:04

I own a gas powered rock drill/jackhammer. This thing uses a mix of 1 part straight 30W motor oil to 12 parts gasoline. I don't think I could think of a better way to foul a spark plug..... .anyway, the only make of plug that seems to survive at all is the NGK's. (I will have to check on the number tomorrow, I'm thinking the base at least is about the right size...wonder if the tractor and drill would use the same plug?)

Mind you, when I'm running the drill hard all day (which seems to be happening less as I start to get away from my prime) I can put a new plug in almost daily.

Straight 30W Engine oil in premix? Wow.

A friend used to work for one of the Japanese motorcycle makers at their Canadian Head Office here in Toronto. He once had the job of "destructive testing" motorcycle engines using premix (might have been injectors) with a *range* of various manufacturers" crankcase oils (as opposed to 2-cycle oils). Under the test load, none lasted more than 10 minutes before severe engine damage.

Now, this was almost 30 years ago now. Maybe crankcase oils have improved a lot since then...

I should likely have gone into more detail, but, it was in the wee hours of the night after I got home from work. This drill basically works by having 2 pistons opposed to each other. The main 'engine' piston is upside down, with the 'drill' piston opposing it and creating the combustion chamber. The oil in the mix is left behind when the gas burns off (at least some of it) and works its way down past the drill piston, and through the drill mechanism. The shanks of all the tools get lubricated this way, and always seem to be where you tend to grab them when you're not paying attention, covering your hand in oil.

Hooker:
This could be a good bet for folks (like me) who have an N that uses a bit of oil. I had no luck with H10's or 12's as they fouled up quick. I have had pretty good luck w/ AL 437's but they still foul up after awhile. How long did you run the NGK's in your 9N? I have used NGKs in bikes and japanese cars over the years and they have always worked well. Thanks for this insight!

i ran them for 6 mos. i do a lot of boxblading and was always oil fouling out plugs on some of my tractors, here in OK we haven't got any snow so box work never slows down and pulling big boxloads full of dirt around puts a pretty good strain on 8-9-2N

Roughstock..... ...why would youask that? Do you think someone else except NGK would make NGK sparkplugs?

And BTW, 3112 is NGK's order p/n for their B4L sparkie which is the equivalent to AutoLite's AL-437 which is the equivalent to Champion's hotter H-12.

And BTW, 3123 is NGK's order p/n for their B6L sparkie which is the equivalent to Autolite's AL-216 which is the equivalent to Champion's cooler H-10.

As a general rule, most N-Tractor owners find the hotter AutoLite AL-437 to be better than the hotter Champion H-12. Dunno why..... ...Dell, yer self-appointed sparkie-meister with an internet sparkie cross-refference guide from NGK

A CRUDE NGK INTRO... in reply to Roughstock, 03-10-2005 17:23:00

back in 1966 the japanese started her up
in 1966 they came to the U.S.A.
(i'm sure they got the cold shoulder)
in 1976 they started mfg. the plugs in the U.S.A.
in Irvine,CA
they mostly run in high rpm motors (boats&bikes)
they were given to me to test out cuz i do a lot of work for and with Orielly's Auto Parts
i didn't like the idea at first about an all american tractor having some foreign parts in it but they being a primary supplier of all my parts and that the price on them was right(FREE)

How'd you get involved with O'reilly? That seems like it'd be really handy to have a decent parts supplier who trusts you enough to test their stuff for FREE.

i sold some hay to one of the HMF'sIC at the district office and he and his wife took a liking to me (don't know why??). it just kind of took off from there + plus i've been buying most all my parts from the same store in tulsa for about 10 years now and with the tractors i've got + 4 cars + 2 work trucks = lots of parts!!!
get to know your O'reilly's mgr have him set you up with a cash account (where no one can charge anything against your account), tell him you want a discount and you give him X amount of your business and he'll help ya out

i got this set at .028 a little wider than normal but i lost my good gap gauge down in the front of a ford taurus doing a tune-up for a friend and had to use an old set that didn't have the right combinations to come up with .025

Hooker,
My 8N 1952 is equipped with a Motorcraft breakerless/amplifier module I saved from my old Meteor 1976/400 CID engine; armature and pick-up coil were saved from a Pinto 1976, modified to fit in 8N distributor (this is not a beginner project). This Meteor was oem without catalyst and spark gap was 0.056"; H-10 spark plugs are set to 0.050" and I have not observed any more carbon/oil fouled plugs.
Gap and spark energy are important for "clean" burning of gasses.

Is it legal to put NGK spark plugs in a 9N? Henry must be rolling over in his grave!
