How to Adjust the Carburetor on a Farmall H

[@deronborghi5929]

I finally found a video that shows the Same carburetor that I am trying to learn. Thanks .. great video

[@jamesmorrison1884]

Hello I agree set all by ear. Sounds good on the video. Great video have a good evening

[@hturbo1007]

I think you did a great job of explaining the adjustments of the carburetor. I set up the carburetor and the timing by ear. My H has a combination of an M and a 756 carburetor, top half M,bottom half 756. Great video, everything was explained in layman's terms.

[@FarmallFanatic]

You ever had that hooked up to a dyno?

[@hturbo1007]

@@FarmallFanatic yes, a dyno is the best way to set the timing and carburetor when you have a turbo. You really need to listen for pinging under a load. By the way, it Dynoed at 53 horse at 540 p.t.o. . It'll dyno around 60 horse if you pull it down some. If you pull it down too much and start losing boost, it'll turn back into an H really fast. Not bad for 152 Cubic inches . I could get some more out of it if I add a water injector, but it's not worth messing around with it for what I mostly use it for.

[@hturbo1007]

@@FarmallFanatic I forgot the most important thing. You really need a dyno to set the boost. Without knowing what the boost is you can destroy the engine, because the turbo can come from the factory at any setting, it could be two pounds or it could be 30 pounds. Maybe this spring I could do a video on the turbo explaining what I did and why.

[@LouisianaTractorworks]

Runs great. Setting by ear is a good way to adjust it when you've been around them long enough. You can hear when something is not right. Have a good week! See ya!

Ting, ting, ting, sounds good to me. Good job👍

Great info! Keep making these H "how to" videos ;)

Great job on the carb adjustments! Over time the vibration can change your settings. 👍

I love watching your vids!!!

[@FarmallFanatic]

Appreciate it

[@alsargent1051]

Thank you for the information, I never knew how to do it on my H or my M .thank God my brother does

[@McGieHomesteadAdventures]

A blonde pushes her BMW into a gas station. She tells the mechanic it died. After he works on it for a few minutes, it is idling smoothly. She says, 'What's the story?' He replies, 'Just crap in the carburetor' She asks, 'How often do I have to do that?'

Thanks for sharing your videos and keep them coming please.

Good video showin how it's done an the sound track o the video backed up all you were saying 💥👍

Sounds great FF. Yeah I burn no ethanol in my 140. It's worth the extra money.

[@larsengraff151]

Exact video I searched your channel for earlier today. Been having problems with my 39 H. Started with the choke getting pulled when I pushed the battery back in after I changed it out. Died shortly after running it, and started burping oil out of the air cleaner. Thought I might of had a stuck valve, so I threw some PB blaster in there. Finally got it started again, but it idles terribly and dies right when I give it a little throttle. Thinking I need to adjust those pins to get it running right again. That or I have the poor thing so out of time and the sparks aren’t firing at the right time. Thanks for giving me a place to start!

[@FarmallFanatic]

Start with the carburetor then go to timing

[@larsengraff151]

@@FarmallFanatic Thanks again for the awesome video! I was able to get my H running the best he’s ever run. I think he still needs a timing, plugs 1 & 3 were covered in soot, but 2 & 4 where basically fine. Still more work to be done. But I was finally able to disc my field!

[@thecollectoronthecorner7061]

One thing many dont think about is the air filter. They clean that bottom cup and fill with fresh oil. However for sixty or 70 years that air cleaner has been catching dirt dust and debris up on the screens . You can take that apart and clean the screens or filter medium with solvent. It possible to have a engine that idles and runs perfect a low RPM. but when demand increases the plugged air cleaner makes the engine run rich. My father bought a 930 case diesel real cheep because it was drinking oil. I serviced the oil bath air cleaner that was severly plugged and it quit burning oil. I knew it wasnt worn out because it did not have any blow by out of the crankcase vent.

[@FarmallFanatic]

That's very true

[@farmerpete]

Listen to your engine, it'll tell you when it's happy :) Good advice to fine tune the power jet under load.

[@daleschroeder8661]

Good idea least it won’t freeze

You might want to try putting a piece of intertube inside the hood for an insulator

[@FarmallFanatic]

Black foam stuck to the inside of the hood

Straight power

[@copperhead6132]

I like the zenith carb on my "A", only one adjustment screw. I run ethanol gas in my "A" mainly because I don't think many gas stations sell it. If the tractor is gonna sit a while, I shut the fuel off and let the gas run out and wait till the tractor shuts off.

[@FarmallFanatic]

It'll save you a carb rebuild

[@deronborghi5929]

What do you use as a lead substitute?

[@FarmallFanatic]

I stopped years ago...once they've been overhauled, you don't need to

[@deronborghi5929]

I have one here from my motorcycle club.And I doubt it has been overhauled. So i've been running a little bit of two stroke oil in it.

[@robertrockwell7581]

you can find non ethanol fuel at boat marinas. boats do not use it. or some gas stations have it. just ask them if they do when you stop in. or if they know where you can get it.

[@FarmallFanatic]

We have it here now

[@mce-jc2mw]

👍 job explaining

[@bradleamon4466]

Is there anywhere that has new carburetors for these tractors

[@FarmallFanatic]

[@ronniewalker2881]

good video

[@deronborghi5929]

I just went through the process that you showed. However, the low idle is completely out. And I'm still getting a very high idle. Now, this is a tractor that never got any attention. Could build up in the carburetor be affecting the idle?

[@FarmallFanatic]

[@weissfarms7680]

What would cause the tractor to want to die on takeoff after carb rebuild it sounds like it’s set correctly but I could be wrong it my first time messing with one . Any advice would greatly appreciate it thanks

[@FarmallFanatic]

I would say lack of fuel... Also check your air passages

I've rebuilt my h carb rough checked timing tried to retune the carb and get bad sputtering when the engine is cold if I try to go to open throttle, once it's warm it's fine. Any ideas?

Have adjusted the valves back to factory settings?

@@FarmallFanatic they have never been touched as far as I know, been in the family since new and not much has been done with it in the past 30 plus years

[@guydaubenspeck9206]

I'll tell you how to fix that Ting Ting Ting of that cap there fanatic and do it right. If those old farmall's have the valves adjusted correctly that just about two or three teeth on a throttle over an idle they'll run in that Capital just float I had an old neighbor who was a dear friend we lost him several years ago here but he can adjust one of those he taught me how he can just one of those so that rain cap would just stay open steadily and just kind of float. So if you have a good head with a good set of valves good spark additional carb adjustment and have the valves adjusted correctly they won't clatter like that. We figure out a way to get some contact information I'll tell you how to do it.

[@FarmallFanatic]

2 or 3 teeth over idle and mine won't ting ting ting either... I had it on the lowest notch possible

[@guydaubenspeck9206]

@@FarmallFanatic well that's a good plan to set those valves up. It is amazing how much better they run when they're properly and completely tuned but it's also amazing how forgiving those old engines are. I have my old BN back in the shop right now when we rebuild it last summer I didn't give too much thought to changing out the fan drive hub and I wish I had it froze up on us didn't hurt the tract or anything but when I found out the small cost it was going to be to repair it I sure kick myself. I was up at the dealer at new bath yesterday picked up a few things and I got a new fan blade for it already had the hub here established it would fit so we got it paid for and squared away hopefully here in the next day or two I'll get that put on the tractor, we are waiting for the radiator to return from the radiator shop and then perhaps we'll be able to hear it run again. But that's his prime example there 8 years old rebuild in the old head and the old block and she went right back to work. Thank you say they don't have to still build them because they built them right the first time

Nothing wrong with your idle adjustment. I liked to set the idle so the generator was still charging at idle. To slow idle speed the regulator will drop out and the battery will discharge.
