Dang it. Thought for sure that it was the carb that was the problem. I went and purchased a pro rebuilt carb. $170 bucks, Even has a new custom made venturie in it.
ITS not the Carb... :-( Idles really nice now though.
Thats the part of this hobby that sucks. I dont mind spendin the ging to replace a part thats bad. No problem at all. But buying crap I didnt need burns my wick.
I may end up rebuilding this whole tractor before I get to the one part thats bad.
I guess its back to the head. I will be pulling that next.
As a side note about Carbs. This guy in Rice, MN that does these. Does real good work. Comes highly recomended. Its a complete rebuild with all new parts. He has custom turned Venturies for pulling tractors too.
Oh well guess the 300 gona wait a little longer.

If you have 100 PSI on all cylinders, then the engine is in good shape.

That leaves only fuel/carb, exhaust, ignition.

Off the wall; pull the muffler and see how the tractor runs.

Keep digging. There will be a very simple solution to the problem.

Kelly, I have to agree with the guys that say fuel flow. Get yourself a 12-oz can and a stopwatch. Remove the plug from the bottom of the carb bowl, and time how long it takes to fill the can. Without going and looking, I would say that the 460 burns around 5 gallons per hour under full load. Now do the math. If you can't flow that much fuel, it won't run right. Also, have you checked for vaccuum leaks yet? The engines in that family, not so much your six-cylinder, but especially the four-cylinder C-200, are famous for it. Before pulling the head, I would take the tractor to a shop and have the engine leak-down tested. This is basicaly a process of putting air pressure to each cylinder with the piston at TDC compression stroke, and seeing what percentage of the pressure leaks out. During this test, you can listen through the intake and exhaust, and you will hear the air leak if there is a burned valve. Same with the radiator, you can look for air bubbles. This family of engines will burn valves all the time unless IH Low-Ash oil is used.

It sounds like the problem occurs when the engine is at less than full vacuum. I don't know about this engine specifically but just using general knowledge. Does the engine have some sort of crankcase ventilation system, PVC system or other emission system? I remember back in the 60's some car engines were designed to activate the PVC system only at less than full vacuum. Have you checked for a dirty or plugged crankcase breather filter, clogged breather lines to the carb/air filter or stuck PVC valve? Good luck.

Try replacing the fuel line. It is not unusual for the old rubber ones to collapse on the inside, closing off the line. Sometimes you can see the line collapse, especially near a bend, sometimes it is inside and can't be seen. Beats rebuilding the engine. This doesn't sound like an engine problem.

Run a compression check before you tear into the engine. The tractor starts and idles great - sounds like the engine is in good shape.

Like the others, my guess is it's a fuel problem. Check the vent on the gas cap. Run the tractor with the gas cap off or swap gas caps. Air cleaner. Pull the hose from the air cleaner to the carburator. Could be the air cleaner is plugged.

I had a tractor that wouldn't run up hill. Took me a long while to figure out that the fuel tank outlet was on the up hill side and that the reserve on the sediment bowl was blocked.

I did the compression test. All 6 cylinders are around the same numbers. about 100 pounds each. Thats what swung me back to the carb.

Slow fuel delivery pulled the wool over my eyes for a long time. I could never get my tractor running right. It was an A Farmall but a motor is a motor. I removed my in-line filter one day.
I don't know why I did it. I was finally able to adjust the carb and the tractor runs great from full tank to empty.

I had a Super C a few years ago that exhibited the same behavior as your 460. I tinkered with it for weeks and finally discovered one of those round spider egg capsules in the tube from the gas tank to the sediment bowl. I don't have a clue as to how it got in there (or why I happened to look there)but it was restricting the fuel flow just enough so that the tractor would idle but if you tried to open the throttle or put any load on the engine, it would stall out.

Sometimes stuff like this is simple but tests your brain logic and troubleshooting ability to find it.

Hope this helps a little.

Actually That was the 1st thing I tried. I pulled the bowl and drained the tank.
Had that happen on the 400 wile I was disking and was a real pain in the butt.
I may revisit the bowl again as I just cleaned it up and reinstalled it.

HR,

Same thing happened to me, only with a Torque Flyte tranny. Darned thing just wouldn't shift.

Come to find out, a prior mechanic had pulled a used output shaft from the salvage yard.

After a bit of diagonising and running oil pressure tests, I finally took 'er down & found that the mud daubbers had blocked off the governor oil feed passage running up the center of that shaft.

Kelly, we had a 560G that hesitated when you put the throttle to it. Put a new cap, wires, spark plugs in it..... ....Set the ignition timing. Now it was better but still not where it should have been. We also had nothing but trouble with the tractors hydraulic system. We had a guy trade a haybine+$$$ for it.

He put a NEW Coil+resistor on it, guess what, it runs like a champ now. Someone asked me if I missed it, nope! I hated working on that engine!!!!!

I know this sounds simple and I am not questioning your ability..but you might want to check the amount of fuel flow from your tank...to make sure you are filling the carb as fast as it needs. Now I work on equipment all the time and my 460U was doing the same thing yours was....pulled my hair out to figure it out. I assumed the new fuel filter was ok but for some reason it didn't allow enough fuel to be delivered. Just a thought...I feel your pain.

Kelly,
I agree with Chris on checking the fuel flow. When you check it, remove the line from the carb and let it run into a can or bucket for a little while. You need to see that the flow will last longer than the few seconds it takes to drain the fuel bowl. I've encountered similar problems, where when I've pulled the line it runs good for a few seconds, then it turns to a dribble. I didn't notice the dribble right away, because I put the line back on the carb too quickly.

Kelly,

Are you getting any dark smoke when she bogs on acceleration and/or goes lame under load?

I rebuilt a Super M several years ago. It had M&W 4� inch yes, four and a quarter inch pistons. We never could get it to run right. I think it just can't get enough air. I would like to try a W9 carb on it but now it has been sold so I guess I don't care.

Kelly,

Have you tried just bumping the timing a little?

There has just got to be a reason for your sorrow.

Hope ya get it figured out,

Do you need a "special situation moderator" to talk you off that ledge? Get used to the continual outflow of $$$. My brother initially just wanted to convert his 400 from a narrow front to a wide front. One thing led to another and many thousands of dollars later...well, you know the drill by now.

A friend of ours brags about his $10,000 JD B. Again, one thing led to another. He claims it wasn't the parts that dog-eared his checkbook--it was all the beer and pizza he bought over the course of 8 months for the dudes helping him get this thing restored.

I've been slowly pecking away at our 460 getting details done on it over the last 3 years. It's really a nice piece now. The latest item was replacing the POS steering wheel that was on it with a correct one including a new POWER STEERING center badge. Strong dollars for both items, but the correct wheel sure makes a difference in how the old beast feels and handles believe it or not. Hang in there. 460s are cool especially when pulling hard.

Who needs pizza? Still, I can get several friends who are crackerjack mechanics to do work for me by providing the beer. Let's see--$15.00/case per beer, vs. $60/hour shop rate....hmmmm....I like that math! 'Course, it's always wise to get the majority of the work done before the majority of the beer is gone, otherwise results can be somewhat less than perfect.
