Farmall C263 governor problem

[rustred]

I agree there is not much to them. I will check out the timing advance and my next step will pull the governor and see if there’s something broken inside. Thank you all.

i hardly think timing has anything to do with a runaway.

and what is that snide remark to mean.

I didn’t think you were the type that does not look at others replies, you must be. Look at my reply #2.

 

[rustred]

have u been into that governor. from my experience they are poor.

On the farm we had a 656, 2 403 & 2 715 combines. No governor trouble out of any of them. Okay that was 35 years ago so the ones still in use now probably have quite a few more turns on them. I don’t think I have ever seen a post on here about someone having trouble with one of those style. Have I been in one, no. I will wait for the UFO report.

“never had one not working correctly” that is why several of us are telling you it is not the governor. Those style are relatively trouble free. As woreout stated there is nothing inside them that slows the acceleration reaction.

First time I've ever heard of an IH governor being "too quick", LOL! And to think M&W and others made update kits and aftermarket governors designed to have quicker response than the OEM units!

Rustred, carefully READ the original post! The O.P. does NOT state that the engine "runs away", his stated problem is that the governor quickly yanks the carburetor butterfly "open" and the engine "falters" rather than accelerating when the throttle lever is advanced and also can't maintain speed when a load is thrown on it. (Speed droop.)

Sorry guys I just got back. The carburetors do not have a solenoid for the main jet the tractors are too old for that. I’ve built a half a dozen IH six cylinder gas engines and have never had a problem like this before. There’s no question about the carburetor at all. They are always set by the book and then fine tuned on my dyno. As I said I switched carburetors with my pulling tractor and the problem did not move. I am not a rookie at this at all, but I have never had one act like this. I’m sure it has to be the timing advance or in the governor.I will check it all out when weather permits and get back with my findings. Thanks a bunch to all of you. Lee

Maybe you said what you said, but didn’t say what you meant. Your tractor is in fact not to old to have a fuel shut off solenoid. Can’t prove this C-263 carb diagram is for a 656 but such as it is, number 29. IH C-263 carb diagram
We had a 1965 656 and it had one. I think the late 60s 403s had them as well.
Maybe you meant it is “to old” in the terms that it was worked on a lot and it got removed along the way.

My engine idles fine and engine runs good but I have to throttle it up very slowly or the governor kicks in wide-open and the engine cannot handle it. When running wide-open and I put a small load on the engine it does the same thing. The carburetor is rebuilt and working excellent so I believe it’s in the governor. I wanted you guys idea before I tear into the governor . I have had a half dozen of these and never had a governor problem before, It is the early style linkage. Thanks for any input.

ok so this is how i am reading your description. "the governor kicks in wide open and the engine cannot cannot handle it" i am reading that as overrevving. so is it overrevving? i dont have eyes on it and going by words. from what you are saying is it goes from idle to boom wide open, is that what's happening? your description of what exactly is happening is hard to figure out. as you say it can't be the carburetor as you tried another one. my thinking is the thrust sleeve is gummed up and sticky in the governor. plus there is a lube passage for engine oil to lube this governor. so if its getting no lube thats a problem. and also you did not say what model of a tractor this is. i am just presuming a 560 . and this is a pic of the governor and carb on my 560 so we are on the same page. do u have a manual?

i cannot see where he is explaining it like that.

rustred : sorry for the confusion. It is a 560. Wore out seems to understand what I was saying. It idles just fine but when I throttle up the governor kicks in and the engine falls on its face. If I very slowly throttle it up I can get it up to high rpm and it runs fine but if I start to put a load on it the governor kicks in and falls on its face. At this point I’m still leaning towards the timing advance. I will check the timing when weather permits because that would be the easiest thing to do first. Thanks again to you all for your time and help. Oh and yes I have quite a few manuals on 560’s. I’m 69 years old and we bought our first 560 in 1961. I have owned quite a few since.

well now that it was explained in plain old English it a totally different story . plus u keep saying the governor kicks in. yes advance the timing a bit . not going to explain all that either, if you have done them engines you know all that. the carb is always last to adjust after point setting and timing. you just missed and important step. kinda puzzled as to why you wouldnt check the timing and advance. and check that main carb jet for turns out as i said it has a lot to do with stumbling 5 turns out and your off the seat. many people only have them out 2 -2 1/2 turns out for light work. . i am right behind you and have been around these 60 series tractor all my life and i do own quite a few also. they are a good simple tractor. plus been working in the field with our 560 since i was 10 years old in 1967.

 

[Lee460]

Thank you sir. I love my 560’s also. We will get it right come spring. Hope you and I can spend another 20 years with them.

Now that you say it is a 560 I apologize, you are correct it would not have a shut off solenoid. I was not around many 560s so when you say C-263 I think 656 & 706 and I have made some recent posts about 656s. I am still going to say that the governor will very likely not cause your trouble. What do you know about the positions of the heat riser in these tractors? You say you have the “known to run right” carb on a puller. Are you sure the heat riser is not in the “heat” position on the manifold on that tractor and it will run okay with a leaner main jet carb mixture? I do agree that the advance check is first on the list to diagnose.
