Did a little disking today with the super m. We'll it got about to run on temp gauge when it started to run rough really rough. So I took off bottom drain plug on carb and there's hardly any gas coming out! Just put all new needle in and adjusted float and flushed out tank as well as cleaning the screen plug that goes into carb. What's the matter I need this tractor to pull the disk ASAP!
 
Have you taken a look in fuel tank? you might of had something floating around in tank and it may have pluged fuel outlet of tank.
 
c farmall does this, usually in the spring. try closing fuel shut-off and re opening. my problem is in that shut off. sometimes, i have to remove the valve and clear the housing.
 
I just had tank off this morning and flushed it out real good but what is a good solution to really get it clean I've never had this problem should I try a inline fuel filter because I take off screen on carb clean it and then re install it it runs fine for a minute and then it gets stopped up again
 
remove sediment assembly from tank and fit a piece of tubing on it to raise the inlet level in the tank so it is above the crud on the bottom of the tank
 
I had a similar problem on my SMTA, I swore it was electrical. It sat for some time before I got it. I have had tank off and flushed it out also, but occasionally it will start running poorly. I take it to the shop and blow air up through to sediment bowl inlet and that takes care of it. It does have a tube up into tank but there must be something that floats around and plugs it occasionally.
 
I had a similar problem. It was vapor locking when the gas temp got around 135 degrees. I was using a see throught in line paper filter. You could see the air bubble form in filter, fuel stopped and shortly after the engine died. I waited for the fuel in tank to cool and the gas would flow in the filter again until it got to temp.

I replaced rusty tank, removed the paper inline filter and problem solved. Gas seems to go throught screen better without vapor locking.
 
I clean my tanks with sand and water ,tie the tank to the rear wheel of another tractor and put 2-6 quarts of play sand (you can get it at Lowe's) use equal parts of water and either drive slowly for an hour or jackup tractor so that tire can spin freely , you will get 4 sides clean then turn the tank 90 degrees and go again . If it is shining on the inside flush with plenty of water and let air dry . NEW TANK...
 
good question, as have to know this first. without a vent she will not get proper fuel to carb.
 
Farmall 4856 Have you used ethanol [10%] in that tractor ,I know people don't like to hear this but ethanol draws moisture out of the air, and puts it in the gas tank. It's a good fuel but you have to use the Blue Bottle of Ethanol fuel treatment to counteract the moisture!
 
If the tank is OK check the sediment bowl assembly(take it apart and clean), check the fuel line,and the inlet screen in the carburetor. The best thing I have found to clean a line, is an old .035 mig gun liner, works just like a sewer tape. Shine a light in the tank,then you will see whether it is clean or not.
 
Been using E10 for many years. Never added anything, in fact we don't have to use heet anymore here in mid Mn. where we get a lot of temp and humidity changes. If you have a dirty tank, get it cleaned or any kind of gas will be a problem. So what is in that blue bottle? More alcohol?
 
Do you have the round screen in the sediment bowl? That should stop the greater percentage of the "dirt/ rust/ crud" and let it settle in the sediment bowl. The screen in the carb fitting should not plug that quickly when the sed. bowl and its screen are doing their job.
 
I would lke to know just how moisture gets thru your vented gas cap. If that the case you just can never drive your tractor when it is raining or even let it set outside when it rains.
 
I don't buy that story either! Why would you add more alcohol to fix a problem that you say is caused by alcohol in the gas! We have always used 10% ethanol in our C with no problems.

all good advice, but ya gotta solve this first. An inline filter won't help this much debris. It'll just do its job, even better than a screen...and then plug up too.
When you clean the tank, don't forget the inside of the metal gas line. Amazing amount of trash in them.
Really troublesome tanks, sometimes after cleaning, a very strong magnet stuck on the outside bottom away from the outlet a bit will grab some flakes and pin them.
When you are flushing an old tank with high pressure water, go medieval on the bottom of it with your rubber hammer.
(If it won't take moderate rubber hammer blows, ya need another tank anyway)
 
I sure didn't mean to imply that useing more or a different alcohol based product would solve his problem. All i am saying is if u use ethanol and let it sit in their ,like over winter, for 4-5 years, The air that is in the tank, will create moisture in the tank, and with the steady air stream thru the vent,in the cap! You might want to talk with a chemist or a chemistry teacher!
 
Disconnect the gas line at the carburetor use a clean container to catch the gas. Should see a full stream of gas from the tank.

If you have a full stream of gas remove the tube fitting where your gas line connects. There may be a screen behind that tube fitting that's plugged with crud. Also make sure your main jet adjusting screw is opened enough. Hal
 
It will create moisture in the tank with regular gas too. then it pools at the bottom gets in the sediment bowl & freezes breaking the glass. E10 won't let that happen.
 
I'm not sure...vents in the cap could be plugged. Leave the gas cap off and see if your problem goes away. I have also seen where over tightening the sediment bowl bail will for whatever reason, not allow the sediment bowl to fill completely or fill too slowly. Might be a couple things to check.
 
I dont have anyproblem with them setting all winter in a unheated building you are just making up a problem that doesent happen. We have been using it for over 35yrs with not any problems at all seems like people with bad systems seem to make up a problem and then blame it on the alcohol
 
Well, then you shouldn't have mentioned it to start with, Mr Klever! E10 has been in use for a long time now, and as been said, I too have never even thought twice about using, or storing it over the winter. BTW, theres more humidity in the air in warmer months than colder months so your argument is moot.
 
drain the gas out and strain it through a rag----take the compleat unite out of the bottom of tank-----flush the tank with water and strain it to see whats in there[i use a camper tank flusher] get behind the baffle too--take the line off and blow it out with air---put it back togeather --you will have to drain the bowl two or three times--- only put a gal of gas in it--if that doesnt help it -revisit that carb float you reset
 
(quoted from post at 05:52:38 09/27/14) Yes I have a vented cap but there's air bubble at the very top of the sediment bowl what's that from the moisture??

No. It's because all of the crud in your fuel tank is plugging the inlet to the sediment bowl, and won't let the fuel flow in.

That or the tank is empty.
