8n 6v front mount spark plugs

I saw a youtube video where it was suggested front mount 6v 8n's should use Autolite 216 non resistance plugs with .020 gap. I was under the impression that Autolite 437 with a .025 gap was correct. But the video said the 437's are better for the sidemount tractors. Video was referencing a hard to start n series (which is what I have!).

Is one plug better than the other? I'm chasing some potential spark and carb issues on my tractor (I have another thread on that), but was curious about the spark plug preference going forward in case i have been missing something.

not sure how to share the link to the video but i think the address is https://youtu.be/sB22u_DWMag

Using different plugs for a side or front distributor seems to be based more on opinion than fact.

I've used Champion H-12's, Autolite AL437's as well as NGK 3112 (B-4l) and got good results from all of them, front or side distributor did not matter.

I'm using Autolite 437's in my 6 volt 2N. It almost always starts before one full revolution of the engine.
 
usually less than one revolution? My tractor on it's best day has never started that easy. Mine has always needed multiple cranks. I must have multiple issues going on.

But thanks for the comment. I'm glad I can keep the plugs I have since they are brand new.
 
Ram 74,I wouldn't belive every thing I watch on Utube to be fact or the best since bread,.020 gap? I don't think so.
I use to use Autolite AL437's But now use NGK 3112 (B-4l) and like the NGK so much better as they are nickle plated and dont wind up being a rust ball at the ends of your plug wires,gaped to .025 or maybe even .030 on one that uses a little oil
 
I've used nothing but Autolite plugs for decades in all my Fords.Last spring I took a recently purchased 96 F150 in to get the state inspection and while it was there I had them put a set of plugs in the truck.The shop is owned by a 65 year old that has spent his life working on cars,trucks and tractors,so he is as knowledgeable as anyone.When he asked what kind of plugs I wanted I told him Autolites.He said that he would not install Autolites in anything anymore after having numerous failures of them for the last few years,so I told him to put in Motorcraft.
The rest of the story goes like this.Las winter I put a new set Autolite 437s in my 2N,which I've had for several years.This tractor has always started instantly and run perfectly.About two months ago it started being a little slow to start,and afew weeks later it got very hard to start,and then got to where it wouldn't start unless I used a 12 volt jumper.It then got to a point where it would not fire a lick.Plenty of gas,good strong spark clean air filter,two different rebuilt carbs,three sets of points,new plug wires and new distributor and coil.Still would not fire a lick.I finally remembered what my mechanic said about Autolite plugs and went to town and got a set of Champions.About all I have to do now is look at the starter button and it's running.
Of course there will be a lot people who will say I'm nut's and that there is no difference in brands of plugs,but I am relating a factual account of my recent experience.I have been working on old cars,trucks and farm machinery for 65 years and have never had this experience.Needless to say,from now on I'll stick with Motorcraft or Champion.
Apologies for the ridiculously long post.
 
That's sort of my point.The plugs I took out of 2N last winter were also 20+ year old rusty Autolites.Todays Autolites are not what they used to be.
 
The new auto lites are fine. Got three years on my most recent set. I use this 8n at least 4 times a month. Always starts and runs.

Yer old mechanic is right BTDT got the shaft from autolite... I have been saying this for 10 years autolite sold there sole to china they are not junk...
 
The OEM FORD TRACTOR spec is Champion H-10, 14mm. Then the industry introduced the Champion H-12, a hotter plug. The AUTO-LITE 437 Plug is an alternative equivalent. The companies have released newer part numbers on both for some strange f-upped reason. The Champion H-12 is listed as #512 now and the AUTO-LITE 437 is the same as the 216. Spark plug gap is spec'd at .025 - .028. Why muck with it? I wouldn't put too much stock in U-TOOB - people have all kinds of opinions and say so, right or wrong. I have used BOTH the Champion H-12 and the AUTO-LITE 437 plugs with equal success in all of my Fords with both; I've never had any issues using ether or. BTW: 14mm is the plug thread size; 14mm x 1.25mm, the fine pitch style.

FYI:

ALL FORD TRACTORS are spec'd as the 14mm Champion H-10 Plug from the N-Series thru the Hundred Series Models and the Thousand Series Models for gasoline engines. Spark Plugs have nothing to do with whether they are a front mount distributor or an angle mount distributor, or whether they are a 3 cylinder or a 4 cylinder engine.

I've used Champion H12's forever. When they get dirty I sandblast them and put them back in. what really makes a difference is the timing. GEt it set right and gap the plugs at .025 and you will be ok no matter what plug you use.
 
(quoted from post at 15:04:46 09/04/19) usually less than one revolution? My tractor on it's best day has never started that easy. Mine has always needed multiple cranks. I must have multiple issues going on.

My 9N usually starts with less than one revolution as well. It has Autolite 437's in it and is a 6V system.
 
Yep -timing is everything. My old retired Ford tractor mechanic friend, still works on old Fords, and always uses the H-10's -buys in bulk. I get whatever plug they have in stock at the time. As I said, I use both and never had any issues with either.
