A nice Old Farmall , the fuel pipes and filters and the rest must be clean .And test the atomizers. And spark plugs .The whole system .Greetings with your hobby .
I have a wd9 rice special. Couple suggestions, drain fuel pump again and always shut fuel off. It also sounds like the gas to diesel is not changing fully to diesel. Check air cleaner fully and definitely put new thermostat in it
Definitely a problem with the governor. Broken spring/linkage, or not connected internally. The rack is not stuck, as the governor is able to adjust the amount of fuel, that is why it is surging. Fuel shutoff doesn't appear to be working either, as smokes a lot on gas, that means fuel is being injected. Diesel throttle should be all the way up for shutoff, down for full throttle. Bleed the water bowl first, and the rear fuel filter, this can be done without the engine running, as gravity feed. Make sure no water in the water bowel. That can also be bleed off with a screw on the water bowl, rather than removing the water bowl. Once the engine is running on gas, next bleed the forward filter, then the injectors, right at the injector one by one, any order is fine. If you have white smoke, that is unburnt diesel fuel. There are lots of reasons why fuel can be unburnt, from sticky values, poor valve seating, poor injector spray, low fuel pressure, cracked head, engine cold. From the way it is behaving, I would say one of more injectors might have poor spray under high fuel flow, as once it warmed up, occasionally when the governor opened the rack, your would get some white smoke, though could also be sticky values, or poor seating. Recommend first looking into the governor and throttle linkage. Get a shop manual, or a parts diagram for the fuel pump/governor, and make sure all the parts are where they are supposed to be (springs and linkages), and not broken. If you get the shop manual it tells you how to adjust the governor and fuel pump settings to make sure they are at the standard settings, if you are not comfortable pulling the fuel pump, and checking/making adjustments, take it to some one that is. I found quite a few good videos on you tube on how to R & R the fuel pump, and keep the timing. Doesn't necessarily have to be a WD9, many models from those years use the same fuel pump, The 600 and 650 as well as the 400, 450 all use the same pumps. Only thing you have to be aware of is that there are 2 types of fuel pumps for all these tractors. Type A, and Type B. To determine if you have a Type A, those ones have a large A stamped on the side of the cover on the fuel pump near where the throttle linkage is. Anything else would be a Type B, unless it is not an International pump. All international/McCormick pumps should have the IHC stamped on them. Another tip, always leave the engine on diesel mode after running it, otherwise the third valve that opens on gas mode, may warp as the engine cools. Leaving it on diesel mode means those valves are seated and can't warp as they cool.
That’s awesome advice man! I haven’t gotten around to it since I moved it this fall on gas… but I will totally be using this msg as a guide when I get time to take another look at it this spring! I appreciate it , thanks
@@Brokeandtwistedgarage anytime . My dad collected this line of tractors, 1920 to 1965. Had at least one of almost every model they made. Gas and diesel. Wheeled and track. Learned a lot from him before he passed. Still have one or two.
@@johnwythe1409 sorry for your loss, but it sounds like you sure learned a lot from him! I’ve revived a few tractors , but this was my first gas start diesel, I kind of just bought it to swap the motor into my td9 , but I’m gonna try to unlock the td9 motor when it’s out and try to put it back into the tractor down the road !
The WD9 I saw on a video when it switched to diesel the magneto disengaged automatically at the same time as the half compression switched over to full compression 🤔
@@bobpaterson1845 I have switched filters from my Donor cat! I’ll order more , I just know for a fact that the rack is stuck. But I appreciate any info on them ! Thanks man !
I freed mine up with kroil. Pulled the side cover on pump and kept shootin it once a day. Week later it worked like new. The guy that said you have an injector nozzle stuck is probably right. She should not smoke white like that even with a rack stuck.
It's too early and too cold of an engine for the white smoke to be coolant takes a hot engine to burn coolant. The injector that is stuck is either full open or full close and probably a stick nozzle just dumping fuel you can hear it missing. Swap the pump it's easy just follow the timing marks and you will be fine seriously.
If you want I may not be close but I'd gladly video chat with you and help guide you but you won't free up the rack unless you open up the pump as they use spring pressure from the governor so unless I open up the cover and force it to move it won't move

And thats called a runaway diesel. This is why you should never run one if the rack is stuck as they will rev to the moon
Sound advice only way to stop the run is cut the diesel after looking for a spanner or vice grips wit a wet leg.

Dont losd it too much as that is how you crack the head it makes the head too hot and cracks between cylinders 3 and 6 and then needs a new head
isnt the rack behind the cover on the injection pump?
Put a for sale sign on it and good luck.
No plans on selling it , the motors going in my 1950 td9 crawler

Thought you said it ran good on diesel? Give it the tlc it needs BEFORE you wreck it!
🤣 how bout I’ll do me , thanks for the comment 👌
Neat.
Change the fuel filters.

the governor in the pump is bad the white smoke indicates a blown head gasket or cracked head which these were bad about doing
Sounds about right
