My WD-45 stalls under any kind of load. It started last week, the float seamed to be stuck because I had gas running out of the carb when the tractor was shut off. After that it ran poorly. Today I put a new load valve in it just because I had it . The carb was rebuilt last year and seemed to be fine. Now it starts up and you have to play with the choke to keep it running when you put any kind of load on it. I pulled the carb and split it and found no junk but when I switched load valves the old one had some junk in it. You can turn the valve way out and it doesn't seem to matter on how it runs. I opened the shut off after I removed the carb and got a very good gas flow. It will run then starts to stall, play with choke and it runs better for a short time. It was single digits today in Wis. Any help would be appreciated. Sorry about the length of this message. Mike

I used to have same problem..drove me nuts. I took carb off for thrid time and did a very thorough clean job with compressed air...took light and looked into gas tank and found a dead hornet at bottom. His butt just fit the outlet perfect ..removed & problem's solved.

You may still have debris in some orfice or vein of that carb, did you total disassemble and clean/blow-out all the passages/etc??

Make sure the float level is correct while your at it. Is the governor working?
By morning you should be in the double digits for temperature if you figure minus 10 or more as double digits. Good luck with the carb. It sure sounds like you have a fuel restriction somewhere. Edited by CTuckerNWIL - 20 Jan 2011 at 8:04pm |

I rebuilt a carb once where I messed up and had the float rubbing the inside of the carb and getting stuck like the carb was full but it wasn't. Bent it the right way and away she went.

I always use a blow gun with the rubber tip on it, so I can get it tight to each hole and then blow through. I just cleaned up a carb this weekend that way that looked horrible inside, and I sprayed it with carb cleaner and then blew everything out and reassembled and it was fine.

My 45 seems to take on water through condensation or somthing. When it does it runs just like yours. Every time I start it after sitting I drain the sediment bowl and let some gas run through and it seems to run good. I do think you may have a clog in the carb.

If you need the choke to keep it running, you might want to check to see that your air cleaner is not plugged - oil cup and wire mesh.

Myron, If he needs the choke to keep it going that would indicate a vacuum leak or a lean condition. A plugged air cleaner will most likely choke the tractor on its own causing a rich condition.

SO Mike, how much slop is in the throttle shaft and bushings? That could make the tractor run lean and a different carb would cure it.

I would think just the opposite; a plugged air cleaner would act like a choke by cutting off the air intake. Are you getting a good flow of gas to the carb? My 45 ran like that one spring after sitting all winter. I took the carb apart and cleaned it but it still did not run right. Took it apart (completely) the second time and cleaned every single orifice I could find with carb cleaner, tip cleaners and compressed air. Worked after that.

Hello MDM1 Possible condensation/water/ice, water will pass ice won't Back to basics open drain under carb does it run good for 10 seconds?? possible main jet ice/ dirt. If you suspect moisture add a can of heet. I assume it's outside, can you move it inside?? Keep us informed.

Lots of carburetors have a filter screen part of the inlet adapter that gets plugged with varnish to starve the engine. I saw one that I couldn't detect air from the 60 psi in my air tank getting through. It would only idle for a minute or two then quit. Its in a place not often cleaned until you've had that problem.

Thanks for all the help and suggestions. I am going to soak the carb in cleaner and blow it out. I really am starting to think my problem may be in the tank. This tractor would do the same thing going up hill sometimes like it just ran out of gas. But I did open the valve after removing the carb and got a steady stream of gas.

You need to check gas flow through the carb out the drain plug in the bottom.

Drain the tank. I had one that would not drain. Bugs in the sediment bowl fitting and an end off a gas can in the tank. Sounds like the problem is in the tank,bowl assy.,or line.

I had a fly manage to make it all the way to the back side of the float valve once. On my CA I was constantly having to fool with the carb, pull it apart to blow out debris. It had a new sediment bowl. What I found was deposits from bad fuel in the steel line were being loosened by the vibrations of the engine and clogging the carb. I fabbed up a new line and haven't had any carb problems since.

Agree with Burgie, Unbolt tank, turn upside down, and remove everything. Clean out tank real well with ? Thinner/Laq.Thinner/gas/whatever.

I read somewhere that you could run a tube up into the gas tank so you could not drawn from the bottom of the tank. I may consider that also. Does anyone know the size of a tube to use. When it gets warmer (-16 right now) I intend to clean the tank and really consider coating it. My problem is my tractor is 2hrs away at my cabin. But I really think something is plugging up something.

I had that problem on my D14. After many hours, I was removing the carb . . . yet again, when I noticed something on the threads of teh gas line. I looked carefully, and where the gas line connects there is a small compartment. Inside there was what appeard to be a piece of red flannel shirt. Been running great ever since!

Sounds like cold weather vapor lock. If it runs well inside where it is warm it needs a shield around carb to keep cold air from fan from blowing on it!

Hello MDM1 Here's the skinny!! 1 Need coffee can etc, 1/2" &11/16" wrenches, teflon tape, 3/8" pipe plug, PIECE OF FINE SCREEN rolled to look like a cigarette. Remove fuel line at sediment bowl, remove sediment bowl assy with can in place to catch fuel, install 3/8" pipe plug, now clean inlet of sediment assy etc, install screen in top of sediment assy, add teflon tape and reinstall. Any drit etc laying near the hole should flush out. Pour the good fuel back in tank Check the tank AFTER IT WARMS UP .

I found an elbow with a screen attached that will replace the elbow at the carb I hope. I will need a nipple. I read about the screen idea before but where can I get a piece of screen? I really think the problem is in the tank. Here is my plan of attack. I ordered new float( I think mine is good-held down in water for 6hrs no rattle inside) a new float needle and seat, a tune up kit and am going to run a tube up into the gas tank about an inch. I like the screen idea but need screen. It will be a week before I get to my tractor. How can I test my coil? You have to love these old tractors or why else would you have one. Love mine.

Just thought! Our airless paint sprayers have screen filters. Just found my screen.

The screen at the carburetor interferes with fuel flow, doesn't help it. It does keep grunge from the carburetor that would otherwise block passages and keep the float valve from shutting off. Gasoline left in the carburetor and screen makes varnish to accomplish those blockages on its own.
The added screen is suggested for the fuel outlet of the gas tank. Where grunge, bugs, and anything that has gotten into the tank by the cap being off or helped by hands of any size would be sucked into the pipe to block flow. Bees wings from corn has been common, along with bits of paper, butterfly wings, wasp bodies, and leaves from plants. Gerald J. |
