My grandparents have a 1943 2N that they've owned for most of its life (they've had it as long as my Dad, born in '45, can remember). It sees light duty grading the gravel lane, sometimes mowing the pasture, and plowing the lane (on the odd occasion that the tractor will start in the winter). I've got a number of questions, but I'll post them in separate messages to keep the topics separate.

While trying to fix a number of things on this tractor, my Dad (the only one who drives it any more) pointed out that the choke knob must be manually held out any time you want the choke engaged. If you let the knob go, it'll spring back to the "open" position. Looking at the choke mechanism, I see absolutely nothing that might try to leave the choke set where you put it.

My dad said it used to stay put before he paid a guy to R&R the tractor a few years ago. Is there supposed to be some part there that got removed? If so, can anybody post a picture or something of what needs to be installed to keep the choke where you put it?

I think that's the last of my questions, at least until I get some responses. Thanks in advance.

Like the others said.. The coke is for intermittant use.. not continual use. If you are continually using choke, you are enriching the mixture.. and providing extra manifold vacume to suck in fuel. Could be anything from a vacume leak:
@ carb halves
@ carb to manifold
@ manifold to block, or cracked manifold

Or it could be a partiall blocked passage in the carb.. or clogged fuel screen.. plugged gas tank vent.. etc.

I've seen some use a clothespin to hold the choke open.. ( rather than fix the problem ).

Also remember to keep your air filter clean..

> Also remember to keep your air filter clean..

The broken oil bath air filter has been removed, and I just picked up a small, conical K&N air filter that fits perfectly on the end of the air intake tube up under the hood. It's pretty small, but it should be enough for a 120ci, low-rpm engine.

I cleaned out several partially-clogged fuel filters today, too, so that may help.

Clogged fuel filters may have been the problem.

( enrichment also helps a weak spark ignite fuel... but then.. I think you already changed your plugs and verified good spark right? )

Obi-Wan..... ...thats the way the N-Choke is supposted to operate. SPRING-LOADED OPEN. There's a coil spring behind the carburator thats supposta keep the choke open unless you manually pull the choke closed. You do realize that starting a cold N-Engine ONLY requires a momentary goose of choke after you start the engine crankin'. (kinda like kickin' yer jeeps carb accelerator pump at start-up). You doubt? Read your N-Ford OWNERS manual.

I use 1/3 throttle and a quick pull after starter motor starts crankin'. Starts good for me on 6 volts..... ...Dell

Guess what? I bought a 52 8N bout a month ago(my first tractor) and have been slowly goin though it and learnin. Mine did the same thing. When I first got it the choke rod stayed wherever you pulled it to. then after a thorough cleanin of the carb the choke wouldn't stay closed anymore without manualy holdin it. there was a ton of gunk behind it where the choke rod is connected. Guess thats what held it in place. Really confused me but I guess thats the way it's sposed to be. Amazin what a little cleanin will do.

Rob..... ...yes, all N-Carbs that I know about have spring-loaded STAY-OPEN chokes. Sometimes they gitts miss-installed during a rebuild. Sometimes the spring hook-em breaks off. Sometimes the choke rod gitts bent and won't slide thru the dash eazily. Naturally, the choke spring is on backside of carb where its not eazy to see or gittoo..... ....Dell

Your choke is not supposed to stay open. It is spring loaded to stay in the "not choked" position. You have come to the right place to get answers, and congrats on the chance to preserve a piece of your family history!

The choke is not supposed to stay closed; if you want choke, you pull the knob & hold it. The choke is only supposed to be used to start the engine. If you need the choke out to run, you have likely got a carb problem.
