We have a WD that has WD45 stickers on it and the man before us put on a WD45 carb, I guess because he thought he had a 45. The motor is a WD motor with the side plate. The weird thing is that when the tractor is going down hill or you back up a hill the motor dies?? Tried choking but won't run, checked out all electrical and it seems fine. I thought the float was not set correct, my book says 9/32 from gasket to nearest part of float and it is correct. I have let the tractor set on the slope with its tail up and fuel will run out of the line at the carb when I break it loose. I am at wits end, Anyone have any ideas?? Thanks in advance, Kent

I'm having a similar problem with my WD45. I just finished rewiring it and it fires up instantly. However, it doesn't seem to be getting enough gas. When I remove the sediment bowl, or put in on very loosely, gas flows fine from the tank. But, when I tighten the sediment bowl on enough so that it doesn't leak, the flow of gas stops. Do I have an airlock somewhere? Plugged line? I also have had the problem with it wanting to die going up or down hills. Anyway, any help or advice would be greatly appreciated.

I was ready to rake more hay today and last night I read about someone on here that was having a charging problem and they grounded the key switch box and solved the problem. I drilled a small hole and used a crimp on connector and screwed it to the box and ran the wire to the + battery post and took her for a test, well my test lasted from 11:00 til 7:30 this eve raking and no problems?? The ole girl has a 12 volt battery and I don't think the generator has been switched to 12 volt. My dad has a Ford style alternator and he bought a voltage regulator and all lights today and now that the hay is done for a while we can convert to a real 12 volt system. If anyone has done this before I would appreciate some pointers. Thanks for the help! WD45, you can stop pacing for now, keep the info coming though. Thanks Kent

WD45,thanks for the link. I was searching last night and found his wiring diagram, it looks pretty straight forward. I am going to get started on it this weekend. Thanks Kent

Mine did exactly the same thing. Mine is a fresh rebuilt 45. I do have mine converted to 12 volts and an msd ignition with electronic dist, so that may help with the electrical question since mine did exactly the same thing, and it couldn't be farther from stock. Anyway go to Napa and buy a 1 gallon can of carb cleaner, the kind you dunk your carb in overnight. Once clean, blow every passageway out, and run a piece or wire from a mig welder through every hole you can find and reblow it with air. Then rebuild it with a rebuild kit. Not only did it totally fix the problem, it starts easier and runs at a lower rpm very smooth without the occasional pop thru the exhaust.

Hope it helps, and if it doesnt, at least you have a brand new clean carb (which can't hurt) and you can focus your attention on something else.

Might be something loose in the fuel tank, floating around, and blocks the opening when going downhill. Also unscrew the sediment bowl base and make sure everything is clean and open there.

Sounds like your carb is dirty. All it takes is a little scum to block an air blled and/or air passage. I would either boil your carburetor in water for a while to loosen any sludge. ( Boiling is a poor man's way to steam clean) Or just soak the carb in mineral spirits if you don't have carb cleaner. Either way you will need to blow out the passages with compressed air. By the way, don't laugh at the boiling trick, I have been doing that for 28 years. It works.

WD45, the carb is brand new and spotless inside and out?? I used compressed air on all passages when I dropped the bowl. I guess it could have picked up something that the air won't budge but why would it just do it when the back is higher than the front?? I read a post on electrical system not charging and someone posted the box that holds the key and light switch must be grounded for it to charge, do you think it may be causing a problem? Yesterday while raking hay when it would die, which was maybe 6 times in @ 5 hours after @ the 3rd time it wouldn't crank over and had to be jump started?? Thanks Kent

Hmm,
Let's rule out the carb. Backing up a hill or going down could be something grounding out. But you said you checked electrical. Sediment bowl being blocked is definately a posibility. I have had that happen with my WD. If not the carb, the only other thing would be electrical. Meanwhile, I'll pace the floor with you.

Had a tractor once with similar problem. Turned out someone had accidentally dropped a piece of bark in the gas tank while filling it. Drove us nuts 'til we looked in the tank. Next time it dies, take a flashlight and if you can, try to see down in the tank where the fuel outlet is.

Yeah I know what you're thinking. . .gas can on truck, load of wood on truck. Tractor runs out-grab can, dump in gas without cleaning off the can. Well, We're learning.
