I rebuilt the carb and I am having a hell-o-va time keeping the old tractor running. Does anyone have any suggestions?
 
What were the symptoms before the rebuild? Could be a plugged fuel filter or screen in your sediment bowl. Without more info as to what you have already tried and more of a description of them problem it is hard to say. Does it stay running with the choke partially on?
 
Prior to the rebuild, it would run for a bit and
then just stop altogether. I replaced the sediment
bowl assembly and found some flakes of sediment in
the line leading to the carb. It can be maniulated
to run with the choke 1/2 way out. but eventually
stalls out.
 
so many things to check,
when it stops, jump off and check to see if you are getting fire to the plugs.

sometimes the old coil can get hot and as soon as it does, it expands and a broken wire will separate, no spark. when it cools down it will start again, do not ask me how!!!!

give the old tractor electrical system a good tune up.

then check fuel flow when it stops,

I placed a inline fuel filter between the cutoff and the carb to be sure I had clean fuel flowing to the carb,
tank can be dirty, fuel transfer transport tank/cans can be dirty.

it just never ends.

always use a funnel with a very fine filter when pouring fuel into the tank,

be sure it has a vented fuel tank cap,
when it stops open the fuel tank cap and listen for a whoosh sound (air rushing into tank) if so someone has placed a non vented tank cap on the old tractor, must have a vented gas cap.

again so many things, will just take time.

let us know what you find wrong.
we may need the information next month.

ask an old farmer buddy that work these old tractors hard back in the day, to come over and look at it, many times they can see things that you have looked over 20 times.

its happen to me before.
 
CJ,
these new type fuel cutoff valves do not have filters on them up in the tank,
the old one's that came with the tractor many years ago did have screens up in the tank.

I ground down a short piece of copper tube and inserted it into the top of the fuel cut off valve so it stuck up about 1" off the bottom of the tank, just to help keep bad stuff out of the fuel inlet opening.

anything you can do to insure you have clean fuel is a must. also these old tractors do not like the new fuel, try to buy the old non ethanol fuel if possible.
 
one more thing, if it runs better with choke 1/2 way out,
that normally is a indicator the carb is stopped up.

I have tried this before, have the tractor motor running as fast as you can then pulling the choke closed, keep it closed until the tractor almost stalls out, then release the choke and let the motor increase rpms again,

sometimes if you do this over and over, the carb will pull the item that has plugged the carb on through.
but do not place money on this working, but at this point its worth a try.

others may think this is not a good idea,
 
I am at the point of trying anything.....it's the simplest things that make you crazy.......Thanks will be going through everything suggested tomorrow.
I will let you tomorrow eve. Seeing how retirement agrees with me......
Thanks CJ
 
While the tractor is running look at the sediment bowl to see if there are any air bubbles running around in it. If there are then replace the fuel cap. I just did this today with mine after going through the same things you have described. I replaced the coil, condenser points, rebuilt the carb installed new filter, etc... Installed new cap today and ran mine for 3 hours without a problem
