Make sure the gas cap vent is not pluged. try removing cap and see if that helps. I had that happen on an old truck.

I had the same probelm with my 9N. Found crud in the tank restricting fuel flow. I blew back on the line with compressed air to get things rolling. Ended up flushing the tank out

Being a "new" carb does not mean it is right....

I noticed that you wrote that you have a new gas filter. The 8Ns didn't have a filter. If you installed an inline filter and it's a good one, not a Fram, it may not let the gas though fast enough. Pulling the choke out would help. Make sure that you have good gas flow.

Well with a new carb it sounds like you have weak spark, by chokeing it you cover up the fact that you have a weak spark. Change the points and condenser plus install new Auto lite 437 sparks plugs

I had the same problem, not spark, not carburator... It was a leaky (cracked) exhaust manifold. Too much air coming in to the mixture. Just my .02

The spark has nothing to do at all with having to choke the tractor..you are straving for fuel...fuel filter, dirt in tank or line, a piece of dirt in carb,maybe line not tight sucking a little air.... but not the ignition

Just to let you know Dell refers to a problem like this one today and again he says weak spark and haveing to use starter fluid to get on to run. So its up to you to have a look see and asked them whats up

Normally I would agree but if you check in the ford 9N/2N/8N forum you will see it refered to all the time that weak spark and chokeing will make them run where as if you don't choke them they don't run and its because of a weak spark. Its also the only tractor I have ever seen it said about, I'm just passing on what is said there all the time. So don't shot the messeager and look in the arcive for your self and you will see what is said there

If it has a weak spark and you pull the choke out it will only run worse.

Having to pull the choke out can only mean one thing the tractor is running lean, that is a fuel problem not spark.

Walt, common problem on the ford N series tractor is weak spark and by chokeing it that makes them run better but doesn't correct the problem. Check the arcives in the 9N/2N/8N fourm and you will see time and time again where chokeing has lead to the fact they had a weak spark. Dell is one that hammers that home about once a day if not more

OLD unless that choke is hooked up to the advance it is physically imposable. I have been a mechanic for over 40 years and believe me I know what I am talking about.
Walt If anyone doesn't believe then I suggest they go out start their tractor warm it up then pull out the choke to half choke position an see what happens.

Walt well if you don't believe me then I'm sorry its a fact on the N series fords, its also the only ones I have ever heard it about. What can I say other then I'm just passing on to you what is said all day long in the ford 9N/2N/8N forum.

No Old! Don"t go telling him to do things which might not be needed until the spark quality has been ascertained - like look at it. If spark is blue and you can draw a spark something like a centimetre, there is nothing wrong with the spark quality and you do not need to potentially superimpose an extra problem on the one you have already. IF the spark is weak and yellow, it is time for an ignition system service - it could be as Old says, but equally a number of other faults.

Well he said it had sat for a long time and he replaced the cap and rotor but he didn't say any thing about the points. So thats why I said what I said but yes I should also have told him to check to make sure he had a good brite blue spark that would jump a 1/4 gap

Clean the carb and all your lines. May also have some buildup around the screen in the settlement bowl.

Its not a Briggs carburetor, preadjusted and fixed. So go adjust the mixture screws for a richer mixture after you make sure there's no leaks at the manifold gasket, particularly the intake sections. Then be sure the fuel line isn't part plugged.
