To gap or not to gap: that is the question. What's the odds of the gap coming out of the box being correct? I know I deserve to be yelled at and have all manner of insult hurled my way for not having a feeler gauge but I forgot to pick one up at the parts store. I'm a newbie.

Posco,
Can't promise they are all like this, but the set that Tim Ezell referred to that we put in my mowing tractor were all perfect out of the box. Tim personally checked each one and they were all just right. Chamption D21s. Might have just been our lucky day!!??

I use Autolite 386, because I get them cheap. (a son married into the auto parts business) Champions are hard to find, in this area. The rare Champion dealers, don't carry D21, and have no interest, in ordering them. Ed

As with Mr. E, I have found that the Champion D21s I have bought have (so far) all been correctly gapped straight out of the box. If you need the tractor before you can get back to the store to buy a feeler gauge, I would go ahead and install them, then pull and check after you have secured a feeler gauge.

FWIW, I have read that the wire loop gauges are the most accurate, but I have gotten along fine for 30+ years using flat gauges (never seem to be able to find a wire loop gauge that has the particular gap I need. The flat gauges have the added benefit that you can "stack" two or more blades to measure a gap that is larger than the largest flat gauge (such as the air gap in the VR).

I was curious to what style of feeler gauge to get, being new. I'll see what the store carries. I bought a set of 386's but upon further review here went and got some D-21's today.I'll keep the Autolite's for a spare set. New alternator, well, a rebuilt referencing the Hatachi part number and a tire iron to break the front tires loose so I can look them over.

Timely post on cleaning the radiator. I was wondering what the best approach to that was.

Great learning tool right here!

I ran Champion D18Ys in my Cub for a number of years. Simply took them out maybe twice each year, hit them with a wire brush, checked the gap, and put them right back in. Just over five years on that same set of sparkplugs. Then I decided it was probably time for a brand-new set of plugs, so off to the store I went. They didn't carry Champions, but told me that the Autolite 386 was 'equivalent'. From the very first set, on the very first cranking, the engine now had a slight 'miss' which no amount of troubleshooting or tinkering would eliminate. For far too long I had simply accepted that I would need new sparkplugs at least three times every year, and some years as many as six. Just today I happened upon two sets of Autolite 3116s and, after having read numerous posts on this forum and others, I snapped them both up. As quickly as I could I put one set in my Cub and gave it a crank. I was immediately aware that the previously ever-present 'miss' was gone, and that the engine was sounding more like I remembered it from the days when it had the old D18s in it.

And just a few minutes ago I found a full box of eight Champion D18Ys that I must have bought way-back-when.
So, if these new Autolites let me down...

I've been using A-C plugs in the Cub. 46's I think. Only changed 2 or 3 times in 50 years that I can remember. Can probably find enough to make a set if BR needs them. Lots of soot as the tractor ran rich for years!

I got the kinks worked out and I can't tell you how pleased I am. I put in some new champion D-21's, a new alt, starting switch, re-wired the entire thing and a new battery. Lubricated everything that would accept oil or grease but the best part is the way it starts. Quite literally, one half a second on the ignition switch and it starts, and I'm talking a cold tractor. The mojo is strong in this one...if not accidental.

Glad to hear your Cub is breathing :big smile:

Feels good doesn't it :?: :D There is something about hearing for the first time a Cub come to life for you and realizing that it is alive because you gave it the TLC it needed :applause:

Rudi

I've been involved in other forums for a long time but I've got to say, this is fast becoming my favorite. The help and encouragement you guys provide is fantastic and it is truly appreciated.

I feel like I want to YouTube the way this thing starts. Snap---it's running. I was considering painting it but a farming buddy of mine talked me into enjoying the 'character' of the hard-earned blemishes it sports. Dents, scratches and all. I think I'll follow his thinking, at least for the time being.

Keep your ear pointed toward northern Maine 'cause I'm sure I'll be needing some more input.

Thanks, Mark
