Farmall H question

[Wyokid]

Been awhile since I've posted. Question on Farmall H: Starts fine, runs good at idle and high speed-carb adjusted- governor synced with throttle. Problem is that when I put it in gear and drive it falls flat on it's face. Tried putting in gear, holding with brakes it will not try to maintain engine speed. Any ideas? I rebuilt the mag last year, timing marks all line up per manual, bad governor

Have you verified you have good fuel flow to the carb?

 

[Wyokid]

Yeah, good flow and float adjusted to spec.

 

[D Slater]

Sounds like a H. Partly kidding, If you put it in forth gear half throttle and take off does engine speed up or sound like it at first and then level off? Or does engine slow down then slowly go back to speed?

 

[BarnyardEngineering]

What was the last thing you did to the tractor before it started exhibiting this behavior?

 

[used red MN]

Good fuel flow to where, if out the carb drain then okay. If to the fuel line at the carb check it at the drain plug. After the initial drain of the carb bowl it should continue to flow and not slow to a trickle. FYI the fitting that screws in the carb where the fuel line connects has a fine screen, this can plug and stop your fuel flow. If that is good sounds like you may have a governor issue.

 

[Wyokid]

Noticed it doing this when mowing last year. Rebuilt the mag for better starting, don't see why this would affect the lack of power

 

[Wyokid]

good flow to all points mentioned, screens and carb filter all clean. Any tips on checking out governor internals?

 

[Wyokid]

if doing what you suggested engine will die, doesn't even try to maintain throttle setting.

If it will maintain running right for a spell (5 to 10 minutes) at half throttle and parked (out of gear), I'd rule out stuck needle valve in carb, fuel flow, plugged filter at line to carb junction, and things like that.

If problem you are experiencing only happens when you put it in gear and let out on the clutch, but it otherwise idles fine and can run like I already mentioned, I would suspect a governor issue.

If you are suspecting that, my advice would be to watch some you tube videos pertaining to it. Not that I'm implying that the friendly folks here can't help ya. But if your are like me, when it comes to governors, it's better to be shown, than have it explained to me. A spring that's broke, or the obvious like that, is one thing to find and perhaps be simple. But if something came loose, wore out, or fell out of adjustment, it becomes more trickier to get back right again. When it comes to that, a video to watch can be of much more help, than a simple typed explanation.

First of all, how did you adjust the main jet fuel needle. Has to be set at wide open throttle. Screw it in until engine starts to falter, then back out until smooth plus at least a half turn more open.

To check governor, take plate off side, check the weights for wear on their pins. Should be very little slop between weight and pins. Then look at the ball bearing that weights operate. It should be smooth turning and no play between inner and outer race. Spring is not your problem unless you cannot adjust to full 1815 rpm. Any wear in other linkage inside governor will give you trouble reaching low idle or high idle speed but not effect action very much regulating engine speed as engine is loaded.

As for the spit and sputter when opening the throttle on an H, that is more of a problem of carburetor changing from low speed jetting to load part of carb and condition of the manifold. Doesn't normally effect engine pulling ability. A lot do it, a lot don't.

As Pete mentioned in the governors the main thing that wears is the weights and the pins that hold them and they pivot on. These are replaceable but you need to know what you are doing to keep the tolerances correct. I would recommend you check with Storm Creek Governors, Bob Lenz Caroll, IA. If you cannot find his phone number email me, I do not like to post phone numbers without permission. I see one company offers a rebuilt shaft for near $180, I would guess he can do better then that.

Put a new spring in the governor. Make sure the holes it hooks in to are not worn too big.

This may not help but I had a similar situation years ago not on a tractor but a 4 cylinder engine. The head gasket let go at the narrowest point between #2 & #3. A compression test is a fast and easy check for this.

 

[Dave41A]

If you feather the clutch can you get it to move at all?

 

[Wyokid]

it will move ok in reverse and first. second or higher stalls out. Kick in the pto and will barely go

 

[Wyokid]

Ok, thanks everyone. I'll open up the governor and check it out. Sounds like he may be the go to guy.

 

[Dave41A]

OK. Mine would die immediately and was in two gears at once. 1st and R are on the same rail. But if the PTO is making it die then that is a power problem. Like the others wrote, it could be a governor problem, but I would suspect either a manifold or carburetor/manifold gasket leak, or even a partly plugged main jet. Does choking the engine help things at all?

Bob Lenz of Storm Creek Governors is the way to go. He has rebuilt three for my Farmall M tractors. Outstanding work. Ellis
