Farmall H question

Hi all. Been a long time, including a couple of tractors and one long-term relationship. Newly-married (first and only time!) and just bought a 40-acre farm with a nice, established 20 (or so) acre hay field. Put a pasture high-tensile fence up for the mules/donkeys/horses and put a new metal roof on the barn (lot of work for just buying it in August.

Glad to be back on here with you all. Missed it a lot. Now, for my issue...we have a Farmall H that has been previously converted to a 12-volt. Start, idles, charges great. Recently, it seems to have developed the habit of sputtering when it gets under load for a short time. If I stop and let it "catch up" with itself, it runs great, including for the first few seconds of having a load on it, then it starts to sputter. I'm wondering if it's a fuel or a possible governor issue? Any ideas on where to start?

Thanks, as always, to Old and everyone else. Glad to see some familiar names on here.

Sorry for the duplicate posting. Meant to edit the first by adding a picture but messed that up. Sorry. Here is a picture of my OTHER tractor, "Hercules".

Nice looking tractor(both). When it gets under load and starts to sputter try pulling the choke out. If that helps it is probably a fuel supply issue. Have you adjusted the load jet on it at all? If it is a supply issue work backwards from carb. Disconnect line there to see if you are getting full flow, if not go back to sediment bowl. sometimes something in fuel tank bocks outlet.
 
Thanks hayfarmer. I will start with that. The "Other" tractor has no supply issues. If it does, there seems to be a very loud warning system. LOL
 
Are those cylinder on that ;loader 2 and or 3 stage as in having more then one part that slides out. I have a set of cylinders off a loader like that on that when closed they are about 4 foot long but open about 8 foot and are 2 or 3 stage. Been to long since I had then extended to remember if 2 or 3 stage. Always wondered how that load was set up since when I got them most of the loader was gone just the cylinders and a piece here and there
 
As one other poster said check the fuel coming out of the carb. If you have good flow there open the high speed jet a 1/4 to 1/2 turn at a time. If you have low flow there unhook the fuel line at carb, if you have a good steady flow there then you problem is the screen in the carb. whrere the fuel goes in. If you don't have a good flow there take the fuel bowel off and cheack the screen for dirt and also check how much fuel is coming out of the tank. You will find a plug somewhere.

You say 12v does the coil have the resitor hooked to it. Then sparkplugs. You say it starts good and after a bit starts a miss. If it was gas it would stopas soon as it ran out. From your description sounds more like spark issue coild,cond then plugs. These new condensers show the same symptons as your problem. Anymore newer cond sure seem to have a problem just never know if you have a good one or not.
 
Poor spark will cause that. First thing I'd do is put new points in it. A bad spark plug will miss under load too but it will be a consistent miss on the same cylinder and you should be able to tell that.
 
Hi guys. Thanks for the advice. Tomorrow after work I will check the fuel flow and then go from there. It ran perfectly up until recently, so I am hoping this is something relatively simple.
 
Common in winter to have to richen up the fuel a tad bit then in the summer back it back off some due to the heat and cold
 
Thanks Old. I used this quite a bit to clean up a barn and field. It started this problem when I was driving it to the new farm we bought, about a 10 mile ride in relatively warm weather at the time. It started pretty quickly into the drive and had done so ever since, about 2 months now.
 
Been a while since I have messed with any of the Hs I have so not 100% sure on this. If I remember right the main jet adjustment is low on the carb and it can be removed in 3 pieces or as a whole. Remove it as a whole then check it out and make sure it is not clogged up and also make sure you get a good flow of fuel out of it
 
Hi Old. You answered a lot of questions about the Allis B and WD45 I messed with through the years. I'm not real familiar with IH's. I'll check the flow through the fuel lines first, but if that checks out, is there a filter in the carb at all?
 
I do not remember if there is a screen in the carb inlet or not been to long since I have been in one of those carbs. I can say if you try this you may save your self some time. Simply pull the carb drain plug out of the bottom of the carb. If you get a good steady flow of gas there for 3-5 minutes then you lines are not clogged up. Catch the gas so you can see if it has dirt/rust/water in it. If it has an odd miss try cleaning the plugs and or even try to move the plugs around to see if the miss goes with a plug
 
You never did answer the question about the hyd cylinders and if they where 2 or 3 stage or just single stage
 
The same tricks and techniques you used on the AC engines will also work on the IH engines. They operate on the same principles... Fuel flow, carburetor cleanliness, ignition components...

Have you had a chance to do any of the suggested troubleshooting yet?

I'm really thinking fuel flow may be your issue. Sputtering after a few seconds indicates that the fuel bowl level in the carb is dropping too much, because not enough fuel is coming in to re-fill the bowl.
