There is a adjustement on the front of the carb. It takes a small wrench to loosen the lock nut then you can adjust this screw. This controls the amount of fuel going through the main jet. In for leaner, and out for rich. This is for adjusting under a load, but if it is in too far it may be part of your prolem. These are a good dependable tractor. My dad farmed with them in the 40's up to the 60's. I still use them in a discing business. I have several. Stan

Thanks Stan,, I will try that. I bought it as a unrunning machine, but the guy said it was running when parked,, he parked it because the cows had pulled off all the wires and ate the seat, he just didnt have time to work on it,,,Jim

WOW !!! what a responce thats good if your a mechanic why would you need advice ? why ask for advice ? if you aldready know ? your knocking my
mechanical abilities HA HA !!! are you requesting
my proof of mechanics license HA HA !!! if your a mechanic you should be able to diagnose a simple problem like that EH !!! i would think the advice that i gave would be appropriate for the simple problem that you asked an answer for !!! but i guess you know better than the rest of us EH!!!
i shoudnt have wasted my time giving advice anyway
you really should consider buying a realistic crawler anyway why would you waste time fixing a
dinasaur like that i dont think it would be wise to spend any money on that junk anyway who uses gasoline crawlers anymore ? i guess your looking for a free ride !! sometimes you have to spend money to have good equipment !!! OH i dont need to
prove my mechanical abilities to you or any one else !!! you are really ignorant arent you !!!!
ask for advice then insult the people that give you advice why do tou need the advice of others anyway it seems to me that your the one that has to fix your machine anyway !!! no body else can unless you reahc into your wallet and pay a professional which is probably what you should do although it would be hard to find any mechanic to work on crap like the machine you have HA HA !!!
two idiots for the price of one !!! two cock in the mouths !!!! Chris thompson

HELLO !!! again RAB vacuum does not leak away like a fluid or whatever you said i imagine the guy that is wanting to fix his machine would appreciate knowing how to diagnose his problem which can be done by actually knowing what your trying to tell him !!! the straight forward steps to fix his machine !!! anyway i am not an engineer
as you said i am a automotive mechanic with a diesel endorsement license and graduated my apprenticeship with high marks and an award !!!
and have worked for almost 20 years in the trade!!
AND HAVE NOT HAD PROBLEMS FIXING PROBLEMS !!! with machinery that i come across heavy equipment automotive transports ect and have operated my own business for the past eight years so to have
you belittle my mechanicall abilities is a joke to
me !!!! obviously you are very SIMPLE !!! with your repairs ? ? but try stepping on somebody elses feet some of us dont need to be SIMPLE to properly fix a problem !!! we know from experience
as you see others posted the same responce as me more than one obviously they know what there talking about TOO !!! OH dont you think if your going to pull a carburetor off and clean it in carburetor cleaner that you should install a kit ?
some people like to fix things right the first time not the fifth time !!!! oh i have had many carburetors apart and not installed kits as you have labled me an parts installer but in the automotive trade today you dont have the opportunity to fix peoples vehicles twice EH!!!
i guess you wouldnt know that as you are surely not a MECHANIC !!! or a business owner are you you just think you know more than the rest of us SIMPLETON !!! try getting an education first and then put five years or more in to get your license
then ad another 15 years on top of that and then i will respect your OPINION !! PLEASE !! THANX!!!

Seeing as though it was me asking for opinions and not you I see no reason why you should rag on him for answering. He said nothing that could cause damage or harm to my machine,,I am also a mechanic by trade and have been for years. I am unfamiliar with this machine and was told to watch out for some parts of the intake system. That is why I posted the question. Some people seem to think they can rule what is posted on here. I appreciate all the answers and suggestions, I also notice you had no suggestions other then to rip on RAB, you pointed out the most obvious answers ,, I would think a master mechanic of your claimed quality would have more to offer... Now I know why I almost never post on this board.....Jim

RAB you cant see vacuum leaks !!! i suggest you use a vacuum gauge!!! to check for vacuum leaks
and to find them take a propane torch unlit of course and move it around probable leak areas carb base intake manifold ect i guess oil would work too ? but the propane will make motor speed up a little and then you have found the leak but ill put my money on the carburetor passages being
blocked and the carb needs a soak in carburetor cleaner and a kit would be wise too !!!!

Chris, I thought all qualified engineers would know that it will be an air (or other fluid)leaking INTO the system, not the vacuum that is LEAKING AWAY.
AND re carb kit - c"mon, typical of a fitter, to just replace parts, especially when they may not be required.

if the machine will run with the choke on it must have fuel flow to the carburetor ? so then the diagnosis is either a vaucuum leak or the passages in the carburetor for the idle circuits are partly block which makes it need the choke to keep running !!! to restore the fuel mixture it needs to keep running some of us have the experience and qualifications to diagnose the problem without being simple !!!!

? - Answer - it might not have enough flow.
Possum is right, except that I would have tried the carb drain first. Try the SIMPLE things first - take the engine apart later.
Like, try spraying thin oil around any possible/likely manifold air leaks before tearing into changing a gasket or whatever.
RAB
Btw when have you ever seen a vacuum leaking? A bit like saying the cold is creeping through something instead of saying it is losing heat!

I have checked the flow and it looks good. I will try the jets next. I bought the dozer this fall and havent messed with it much,, it has new pins and bushings and a hydraulic winch on the back,, nice cage over the seat as well,, I got a good deal on it so I bought it unrunning,,,Jim

You"ve got a clogged main jet in carb or one of your pathways inside carb.
Do you have a tip cleaner kit for your torch?
If so get one and clean out your jets and all other orfices in your carb.
If you have a carb dunk set-up with carb cleaner in it ,let it soak for a couple of days.
also check and make sure you are sealed good on your connection between carb and intake manifold (gasket on carb).

Disconnect the fuel line from the carb. If there is not full flow, the problem is upstream. If there is, re-connect the line and remove the drain plug fom the carb. If there is not flow then the needle and seat need help. If there is flow, THEN remove and rebuild the carb.

Possum,
Right on the button. A little simple diagnosis is much better than flying blind and going round in circles....
