Help with Carburetor on A Cub Cadet Wheeled Weed Trimmer

wsmm · Jun 11, 2022

Having problem with my Cub Cadet Wheeled Weed Trimmer this year. Will start on staring fluid or carb cleaner, and runs strong for a few seconds then starvse for fuel. Have started working on it, have removed the fuel line from the carb and get good fuel flow from the tank, Believe the carb needs a cleaning, as the Gas I put in also was put into another wheeled trimmer and it runs fines. My problem is the the fuel bowl has two bolts on it. One on the bottom and one on the left side looking at it from the air intake side. I need to know what the two bolts are for before I try to take something apart and break it. I believe the bolt on the bottom is to remove the bowl. but have no idea of what the bolt on the side is for or what sequence to take the bolts out in. Haven't been able to find out any info on line.
Thanks for any and all help,
Bill

I have a 3 year old cadet wheel trimmer also. Mine the center one holds the bowl on and the outer edge one is a fuel drain. That is how mine is. The drain one came out of mine and had to purchase another.

One is probably just a plug. But to be safe just take both out.

Probably going to find the carb gummed with dried fuel residue. Good chance it can be eased apart, cleaned, and reassembled without needing any parts.

Locate the main jet, it will be either built into the bolt that holds the bowl on, up inside the center stem, or in the side of the stem. Clean it thoroughly with a stiff wire. Spraying and blowing is not enough, even if it looks clean scrape it thoroughly.

wsms,
The side bolt is for draining the bowl. Sometimes water collects at the bottomof the bowl and closes the emulsion tube fuel inlet. Water being heavier then gas will drain out of the side plug first.

Try that first, catch what comes out of the plug. If it's 100% gas, then you need to clean the carburetor. I am betting it's just water at the bottom of the bowl. Give it a shot, you might get lucky.

Post back if you need more help,

Guido.

What kind of engine? We have a Cub tiller and it has a Honda engine, and it wouldn't start this spring. It had a complicated fuel system, with a fuel pump, and seemed hard to take apart. But, on closer inspection, the whole fuel system came off with 3 bolts, 1 hose and the governor linkage. I then took the bowl off the carburetor, ran a torch tip cleaner through the main jet and any other small orifices. I put it back together and put some Seafoam in the gas, and it started right up and has worked fine ever since. Good luck with yours!

Red arrow points toward drain plug.
Yellow arrow points toward bolt that holds the bowl to the carb body.

If your main jet is inside the stem (most probable) it can be removed with a common screw driver after the bowl is off. A twist tie from a bread bag with the outer paper/plastic removed is a nice size for cleaning those little jets. Torch tip cleaner works better, but without one the twist tie thing works pretty good.

Update:

Took the the carb off, celane out the jets with welding torcg cleaner, sprayed with carb cleaner and put back together. Runs fine now. Thanks for the help.

Glad to hear. It gets easier after the 2nd or 3rd time.
