Ford 900 Carburator Help TSX-769 Sputtering Out

I am in my 30s and just moved to a homestead. I was gifted a beautiful Ford 900 high crop tractor with a loader. The tractor starts very strong and runs great for 15 minutes then starts sputtering out. I replaced the coil and plugs with no luck. Next I rebuilt the TSX-769 carburetor and with my luck I sheared off half of the Carburetor Adjustable Main Jet inside.
I want to just get a whole new carb but the prices are outrageous! from $325-$500. Is there any other cheaper carbs that can fit on my tractor? Thanks!!

Best bet would be to find an experienced "pro" locally that could repair it for you, also there may still be one or two reliable guys here that will reasonably "repair and return" it to you.

Otherwise, you will have to "bite the bullet" and buy a new or re-manned one.

But the "convention wisdom" of many of us here is to keep it and repair it, as it is a good American-made part that is a part of the heritage of your tractor.
 

As wore out said there are guys on the site here that do great work on them at a reasonable price. It sounds like your sputtering out problem is fuel flow restriction. To check it you remove the drain plug from the bottom of the carb, then turn the gas back on and catch it in a can. You need to have a pint in two minutes. Most likely your carb WAS ok. It is unlikely that your 900 is a high crop because they are very rare. It is most likely a row crop. I have one.

What do you think it could be if not the carb?

Whats the difference in the high crop and row? Mine has 2 front tires close together and is substantial higher than my father in laws 900.
 
"sheared off half of the Carburetor Adjustable Main Jet" What does that mean? The adjusting stem is threaded on top into the top half of the carburetor. Isn't that easily repaired? It is available through a parts house. I would sure fix the original carb if all possible.
 
I tightened it a bit much and it sheared. I would have to find a way to back it out. Like I said I am not good with carburetors and if I could find someone to rebuild it that would be best.
 
"The tractor starts very strong and runs great for 15 minutes then starts sputtering out."

An exact description of the 641 I bought two years ago from a dealer who is a friend. He installed new points, condenser, and plugs before he delivered it. It was the condenser.

You need to have a pint in two minutes. If it is higher than your father-in-law's 900 then it is probably rally a high crop. Usually people are noticing that they are high compared to a 600 or 800.
 
"if I could find someone to rebuild it that would be best."

My email is open on modern view.
Send me an email and we can work something out.
These are pictures of one of the 769's I have rebuilt.
I then put them on my tractor and test and adjust them for you.
All you have to do when you get it back is bolt it on and go.

Main jet screws in the bottom? Should be able to get it out. If not I have a parts carb. Bottom half is good. No jet. Would have to buy a rebuild kit that has one in it. Email me. My email is on classic view. Got a picture of your tractor? Live to know if it is a high crop.
 
"Main jet screws in the bottom?"

Where the main adjuster goes, through the top or in the bottom,
depends on the actual model of the carb. This size/style carb would
not be original to a 900, but may be for a 901 or early 4000.
It would fit a 900 with the right manifold and add a little HP when
adjusted correctly. All three models used the same engine AFAIK.

P.S. if that's the adjuster needed, they can be bought seperately.

Here is a picture of it. Let me know if it is a row or high crop. Thanks!

That is a somewhat regular looking regular row crop 900. I say somewhat because it is much better looking than most. Now that I think about it I don't believe that there was a high crop 900 built, because the high crops had a high arched wide front which was not available until the 901s came out in late '58, when the two piece pedestal was introduced.
 
It does have XX1 fenders on it however. I'm uncertain if they are 901 fenders or 801 fenders. It appears they sit too high which suggests that they are 801, the difference between the two is the bracket.

Nice looking tractor.

Loader not as much. They've not been a pair all that long.
 
pomester, I agree, it's a nice looking tractor and the fenders are not original.
I can't tell exactly what they came off of, but definitely not 700/900.
The 700/900 fenders are unique in that they are curved and were notched to
fit around the axles. Not just the brackets, but the sheet metal is different too.

As far as I know, they are the only Ford fenders in that era not repopped.
I can buy standard 9N/2N/8N/x00/x01 fenders aftermarket.
(not the early 9N two ribs, but they aren't in that era)

I searched for about 5 years to find a repairable set for my 960.

I also included a picture of a 900 high crop.
AFAIK, the two piece pedestal came out near the end of their production.

(quoted from post at 16:44:14 01/05/21) Any updates?? Any plan?

Yes! Royse will rebuild the carb for me. I was able to back out the sheared jet adjustment.
If its not the carb I will change out the condenser.
 

Thank you! Your right, they have been pair for about 3 months. It sure is good at moving snow. I have plans at painting it this summer.
