44 Model B running rough

so The carb on our 44 Model B (all fuel) is giving me fits. I can usually get around in 1st gear and sometimes 2nd/3rd. But anytime I put it into 4th,5th, or 6th the tractor stumbles as soon as I let the clutch out. I can feather the clutch and keep it running but I can t let the clutch out and drive away. So essentially with a load the tractor dies. I m out of options and need some help/guidance. Here is info on tractor/things I ve done.

Carb is a DLTX 34
Magenta is a WICO X
Carb has been sandblasted clean and passages blown out. Rebuild kit installed. Tried a new condenser (x5614).
Load needle is 1.5 turns out.
When running in 1-3 for a bit carb is cold and starts to sweat (healthy operation)
Idle sounds great and I can get it really slow.

JUST noticed the choke pin (what the butterfly mounts into) is leaking gas/sucking air and the screw next to the idle needle, and another screw seams to be leaking/sucking too. When I say leak, it s wet but not pouring out. <- is that my main problem or a separate problem and can I fix that or with all this info as I pigeon holed into buying a new carb? Thanks for the help and sorry if I left any info out.

Posted pics with circles show where s leaking.

Those drill plugs need to be sealed with dope and tightened tight. NO they can't "leak". Only thing that may be coming around the choke lever would be oil from oil bath air canister. Make sure you got the load nozzle pushed all the way up it's bore so you can see at least 3/8 - 1/2" protruding into throat. Sometimes you have to drive it up with a driver. That being down will cause it to fall on it's face when accelerating or loaded. One turn out on load should be enough for any of them. Very uncommon they have load issue. Usually idle issues. Let me know wht ya find. Be glad to help or re-build if needed.

When did you last give this tractor a
good ignition tune up? Stumbles under
load is classic weak ignition.

You might consider removing the oil cup from the bottom of the air cleaner.

If your tractor runs better with the oil cup off, then the air cleaner filter body may be clogged.

Take a look at what came from the oil cup of our 43B.

Hope this helps.
 
I could see liquid being pushed out and I could hear air leaking as well from those 3 circled areas every time I rotated the flywheel. All smelled like gas.


Pardon my ignorance but what do you mean by ?load nozzle needs to be pushed all the way up"? Because the following details didn't make sense to me.

Just my luck that I have the opposite of the usual problems lol
 

Sorry I should have mentioned too, the tractor ran just fine before we cleaned it up. So essentially I took the carb off, rebuilt it with the kit and put it back on. I could only run at wide open throttle. learned the needles weren't working. That is when I sandblasted the carb and blew everything out. We got the tractor to idle amazingly, and it ran with a load for a few days. Then I couldn't run anything past idle. Figured MAYBE another be of rust or dirt got clogged up so I cleaned the carb again. Idled again just fine but cant run under load. Changing the load needle does affect the engine but I tried 1.5 turns out all the way to 2.75 turns out. I believe I went down to 1 turn out but cant recall. I will give 1 turn out another try.
 
Because most people when they insert load nozzle back in after having it out for cleaning, are afraid to take a driver to it for fear of hurting it. They usually do not just "fall back in" where they came from without taking a little driver to them and seating them all the way up into throat of carb. Look into end of carb. If it's up in there 3/8 " at least, then it's ok. If not , it needs drove up in there.
 
I guess some call it "load jet". It is not a jet...it is the load nozzle. A jet restricts fuel to metered amount. This nozzle is a reservoir for instant acceleration and also mixes air / fuel and serves it up to the carb throat at times of load or acceleration.
 

Ok thank you! I got called out of town for work so it will be a minute or two before I can get my hands on the tractor but I will update this thread once I try that. I m not going to leave this thread hanging because I need to get this running lol

Ok forgive my ignorance with what I have done today. Frustration is a fickle thing to deal with.

So I tapped the main nozzle with a 8-32 tap (didnt seem to bite much).... bolt stripped out in no time. Tapped it with a 10-32 and nuts kept breaking the threads off the bolt. Tapped it 10-24 broke the bolt in half. inserted a 12" long 10-24 threaded rod. Used a small socket for my base and a deep socket for a slide... made a make shift slide hammer. Main jet will NOT move. Caught my palm in the slide hammer so I called it a day. Had it soaking in PB blaster for most of the day. Dont know if tapping it larger just ruined it but its done now (looks like worst case scenario I can buy a new one from Davenprottractor.com)

Do I need to let it soak longer? Or try something else? Buy the actual slide hammer removal tool? (https://www.external_link.com/p-475-carburetor-jet-removal-tool.aspx). After speaking with Randy on the phone it sounds like the main jet being clogged is probably my issue so I really need to get it out.

Any suggestions to help get this main nozzle out!?
