 Topic: 160 ci Spark Plugs
Posted: 04 Mar 2017 at 4:37pm |

Okay, want to run some errands tonight and cannot put my hands on spark plug info for the Series Two. Ended up putting in new Champions last fall and she does not get much work winter time but they are already done.
Anyone have the Autolite and NGK numbers handy?
Thanks in advance.

Thanks T!
I have no recollection of when (or why!) I bought those champions but it had to be some years ago and I found em' in the parts locker so threw em' in.
Total junk and I know better, the old gal is at approximately 15K hours and I started wondering if she was gonna finally make me park her until at least rebuilding the dist. gov'ner and head job as that is when she will get the crank pulley retrofit for the 415 loader/pump.
Bettin the new 303's bring her back around.
Not that I need another reason to put the re-work off before I lose the dist. weights but then again, that new to me late 185 keeps callin me to stretch her legs.

Would be nice to see pics of the plugs. Can you post? What is wrong with them? Motor not running or engine miss?

Old stock champs are ok,---BUT the new (mex.) mades are junk right out of the box!---Buddy put 3 sets in his 180 and it still missed, so he took my advice and put ac's in and tractor had front end lift upon fast clutch dump! ----No more miss either!
I use ac or ngk for myself! thanks; ac fleet

Ed, she developed a miss within 30-45 days and I wrote it off to chasing bad gas again. She sits in the winter other than putting out round bales, a little land clearing pulling cut limbs to the burn piles on the lease pasture and occasional blade work. Never had to choke the old girl over the years as 1/4 throttle and she would pop right off, even at 25-30F in winter.
Autolite 303's brought her back around quick, set at the originally recommended .25. Champs were loaded up with carbon as she was not burning clean (or hot enough during short use or 30 minutes or so) with rearmost cylinder the worst.
Will see how the AL 303's do as she had NGK's in her for ten years prior to the Champions.
Quick fix for 8.00, and 10-15 minutes work.

Champions *might* work, but you have to go a couple of heat ranges hotter than specified. It's just not worth it. And no, they don't work any better in Farmall tractors. Ask me how I know.

My autolite book says 85, which is a projected tip. Specs same plug for the wd45. I have had good luck with 295 and 303 as well, but currently run the 85 plugs and am pleased with how it starts and runs.

.25 seems tight to me, might check that spec again. I was thinking more like .30 or .35 maybe the wider for a more wore engine. Maybe my memory has went on me.

Dave, .25 was the original specs so I will run it there a tad and see how the old girl does on the 303's. I had played with the Champs, initially at .30, then opened up to nearer .35 as she went down hill progressively. Also did a fair amount of testing different fuel additives like StarTron, Lucas and Seafoam while running Valvoline oil for years.
She is very high hour (this is the one you and I picked up in 2006 with the tach broke at 4999) and if the AL 303's act up, I will go back to the NGK's that were in it for many years. Found spark plug extenders in the girl when I bought it and left them in for a few years. Cleaned the old NGK's and put them back in without the extenders and she ran a long time. She did plenty of commercial brush hogging, cleared my place and has disc'd/seeded 2X/year the last four years.
Switched her over to Rotella about three years ago and she had been Seafoam'd to clean her up when I first bought it. Still gets a shot of Seafoam about every third oil change and I try to keep her at 150-200 hours max between changes. The air filter found in her when purchased was dated 1973 and she has her NAPA filter cleaned constantly along with the radiator.
She is kind of like us, plenty of hours and still limpin on!
She will get less run time now that the 185 is here and when I get around to it, re-do the head, replace the gasket under the front bolster and make a new pivot pin when she gets torn down for the 415/pump retrofit on the crank pulley.
She owes me absolutely nothing as she has done plenty for a 1700.00 tractor!
