…… 1953 Farmall Super M

Need some help please!

'53 Farmall Super M. I cant keep it running, it wants to stall when I try to drive it. Idle is very rough, backfires, sounds like crap. I can get it to go 3 or 4 feet then it tries to stall. I push in the clutch and have to let it idle back up again. Also drops the idle when I raise the arms or the back blade. For some reason, it likes running in reverse better. Smells like its running rich.

I had someone fix the choke lever a few weeks ago, and it ran great until this past weekend. Wondering if this new issue is related to the carb? I dont know if these tractors have a fuel pump.

Any ideas of where I need to start looking to fix this? I really need it running to move hay for my stock. Bonus points if you live in my area and can give me a tutorial on the whole tractor!

Thank you!

This could be several things. 1st check your carb , fuel lines and sediment bowl. Is there any sediment in the carb or large amount in your sediment bowl? When it is running do you see fuel pumping through your sediment bowl freely is your carb moving fuel? Check all your lines and empty your sediment bowl, check your fuel filter to see if you need to clean it, if not. Your carb could be gummed up. You can clean that also.Check your vent on your gas cap to see if its plugged


could be the timing which may need to be reset. Also may be the points or plug need to be replaced. Make sure you mark a line where the rotor is and on the actual placement back on the tractor when you take it off to check. I can refer you to you tube for help on doing these. But someone on here I know can explain it far better than I. Wish I was closer I'd come look at it for you.

Could also be the carb needs to be tuned since it's running rich, it really sounds like a carb issue to me, and you've got some good advice so far. Unfortunately you're too far away for me to take a look at it.

This time of year, it seems I'm changing the fuel filters on my diesel tractors. You probably already did but I just mention it cause it sounds like it.

Have not changed a fuel filter, not really even sure if it has one LOL. I know it has a sediment bowl as mentioned above, but that looks clean. I'll take a better look when its brighter outside.

P.s. here's a fuel pump replacement kit if your not getting any fuel "IHS164 Complete Fuel "IHS164 Complete Fuel Pump Repair Kit?gclid=Cj0KCQiA8ICOBhDmARIsAEGI6o1n MfeD73whbqmF36WNfrbiWG_3EOCCZsZrGjAM J3I_0PIEZzwkYaArIQEALw_wcB" https://www.steinertractor.com/IHS164-Complete-Fuel-Pump-Repair-Kit?gclid=Cj0KCQiA8ICOBhDmARIsAEGI6o1n-MfeD73whbqmF36WNfrbiWG_3EOCCZsZrGjAM-J3I_0PIEZzwkYaArIQEALw_wcB

Its getting fuel as I can start it, and it will sit and idle without help. Thank you for the link

Condensation, maybe.
This time of year with warmer days and colder nights makes water.

Get a bottle of dry gas and try that.
I have a 49 Farmall Cub and need to do that occasionally.

Drain the sediment bowl.
There is a small bolt on the bottom of the carb.
Remove it and drain the carb.
Be careful.
There is a little gasket on that bolt

Shut the gas off before you do those things

Hope this helps.
I think this will solve your problem if it just started

Everyone is right that it could be many things.
Sounds like it is barely able to get enough fuel to idle and not enough for any power.
I would do the things others have said above with one change. Have the gas turned on when you pull the drain plug on the bottom of the carb so you can verify that plenty of fuel can at least get that far. If the gas just drips out of that plug hole then you know the fuel problem is between the tank and carb. If the gas runs out then you know the fuel problem is in the carb (if it is a fuel problem).

This might help you locate parts like the filter and such. Walk you through some basics. Fairly similar tractor. Your fuel filter is a metal canister attached to the fuel line that contains a filter. I can't recollect where it is or what type on a farmall but you'll figure out out I know.

Excellent piece!

OP, down load that and get the manual, good stuff!

I didnt take much time to mess with it today, its bitterly cold outside. 8 degrees.
I did open the fuel fill, and there was no vapor lock.
I cant see thru the sediment bowl, as it's coated in crapus on the outside. I'll get some washer fluid tomorrow and wash it off. There is no inline fuel filter. It goes fuel tank, sediment bowl, fuel line, carburator. Would the fuel filter be before or after the carb?
I could have sworn my hubby had a manual here in the house, but danged if I can find it now.
Cant watch the video's, I have no sound on my computer (yeah, a whole nuther problem). I'll try to watch on my phone.

I don't think you have a fuel filter.
You could add one. My 1949 Cub doesn't have one

I'd suggest you take the sediment bowl off and clean it inside and out.
It's pretty easy.
There is an L shaped rod on the top side.
Screw it in clockwise to shut the gas from the tank.
Then loosen the screw on the bottom of the glass and slide the wire thing off.
Be careful not to drop the bowl

I have a 50 year old Deere gasser. I'll walk through what I'd to to Scoop if he did what you describe.....

Start and idle but not get up and go, and 'smells rich' narrow it down to either a weak spark or restricted fuel flow. Take a rag and wipe the glass bowl down where you can see through it and see if it has a settling of crap at the bottom. Look for that as well as a shimmery quality to seeing through it, which can indicate it's collecting water in the bowl under the strainer from condensation. I'd suspect fuel first, somehow.

First thing, check all the linkages from the choke and throttle knobs and make sure they're still all attached and pushing and pulling like they should. For instance, your choke could be sticking and when you push the knob in, the linkage is bowing instead of actually pushing the butterfly back open. Look for the most-recently monkeyed with components first. Mr. Murphy loves to visit when we humans monkey with stuff ;)

Then take the bowl off and, if you can get it off full, pour it into your cupped hand. If it feels colder in some places than others, then it's got water in it. The only solution to that is to keep the fuel tank completely full every night, to keep the inside wall of the fuel tank from being exposed to cold air and condensing out water vapor. Either that or drain the water before trying to start it up, each time.

If you pour it over your hand and it evaporates uniformly and relatively quickly, there's no water and you've ruled that out. Regardless of that outcome, look up in where the glass bowl seats. There should be a screen there. It is somewhat see-through. If you can't, it's dirty. Could be passing just enough gas to idle but not enough to run with a load. Can clean that screen with carburetor cleaner sprayed on it from the engine side. (In other words, like you'd do any strainer--backflush it) Then shake it to air-dry it and reinstall it and the bowl. When you open the fuel valve back up, it should fill fairly quickly if the fuel in the tank is higher than the top of the glass bowl.

Next, there may be a petcock on the bottom of your carburetor. Open that and catch what drools out in something and inspect that for water, same way you did the glass bowl. I'm betting you're going to find condensation somewhere. Then try running it again. Might've been something in the fuel that you didn't notice, and might run fine. That is what I call the PFM Principle of mechanicing. (Pure F***ing Magic LOL!) I don't question it, I just thank Mr. Murphy for his departure and go on about my bidness.

If it's still being stubborn, then it's time to check points and main jets in carb and float adjustments and all sorts of involved stuff which might or might not be the same as my Deere. I'll be happy to add more free advice any time, but just keep in mind it's not Farmall specific and never will be (I've never messed with one) and it could be worth exactly what you're paying for it :D

Good luck, and wish I could be of more help!

ETA I've had lots of good experiences with the folks at YtMag. Been using that resource for probably 12-15 years.

Alrighty. Pulled the bowl, it had some sediment in the bottom. Not what I would call a lot. Saw no evidence of water as described above. Cleaned it inside and out. Screen was very clean. One little dab of goop that wiped right off. Totally can see thru it. All put back together. Added dry gas to the tank also.

It has taken about 8-ish minutes to refill the bowl though. Is that normal? It came out in 2 second streams, like milking a cow, only shorter bursts LOL.

Choke and ignition rods are all where they should be.

Opened the carb and let the gas run out into a bowl. Saw no evidence of water.
Tried to start the tractor and it tries to turn over but never catches now. It has a magnito.

As for the slowly-fillin' sediment bowl, that sounds like a fuel line obstruction.

Where or what does the “float bowl” reside? I’m not familiar with that part.

Sediment bowl is directly below the fuel tank. Very short little connection between the two. Would something like that require emptying and pulling the fuel tank?

Not familiar with that carb. Usually the body of the unit has an area which fills with gas and the
float simply regulates how much fuel is contained therein. If the float sticks, that'll cause problems. Tapping the side of the carb with something can loosen things up. A screwdriver handle is usually sufficient, as some folks wanna used nothin' smaller than a singlejack, which might be a bit of overkill.:cool:

I think you should be getting a steady flow into the sediment bowl. Try taking the gas cap off and see if it comes out of the tank faster. Not sure if the gas cap is vented, if so it may be plugged.

Here's a thread with some other suggestions: super m fuel trouble - Farmall & International Harvester (IHC) Forum

I did loosen the fill cap when it was slowly going in the bowl just incase I was getting vapor lock, it did not change the flow rate. Thank you for the thread suggestion, I did read thru it. Some good info there.

Did you check your fuel lines? If you know how, shut your gas off at the tank and pull your lines off. We blow through them with an air Compressor. If their plugged or blocked you can use a thin wire to clean them out. Or get new fuel line which a napa should be able to supply you with.

The fuel bowel should fill almost instantly. You definitely have an obstruction in the fuel line. need to remove the fuel tank and clean it thoroughly. Take the time to remove the float bowl on the carburetor and clean it. Another thought, Ice.
Is it possible water has contaminated the gasoline? Heet or something similar may help a lot.

Farm tractors are designed to be as simple as possible. Get new points and install them as well as a new distributer cap, wires and spark plugs. make sure the carburetor is clean. Spark fuel and gasoline, it will run.
