Craftsman 25cc Gas Line Trimmer - Answered Questions & Fixed issues

When the Craftsman Weedwacker starts in idle and then stalls and the primer bulb will not fill with gasoline or will not pop back after being pushed in, then you have a blockage within the carburetor. The bulb is intended to **** fuel into the supply line, to prime it. To solve the problem, remove the carburetor, open the side that has ONE screw holding it (not the side with four small screws), remove all the two lines remembering how they were attached (the feeder line from the fuel tank attaches to the straight copper tube and the tube going to the bulb intake side attaches to the bent copper tube) and blow out the material blocking the fuel flow inside the carburetor. Then after replacing the carburetor, press the bulb and it should **** and discharge fuel easly. I have had two of these and the fuel path within the carburetor clogs easly. Jim Hart

fit a diaphragm kit in the carby
the pump diaphragm is the first to fail and then the float diaphragm distorts and will not let in enough fuel to keep it running

My Yard Works was set at the factory to run with the choke partially on. They said it has something to do with the air pressure where we live. Otherwise if it has to have the choke on full then there should be a screw to set it so it will run with the proper setting

Sounds like the carb is getting clogged. Drain the old fuel and make sure the fuel filter is attached to the fuel hose inside the fuel tank. SeaFoam or a product called Start will sometimes clean the carburetor. If not, you will need to have the carb rebuilt, flushed or replaced.
Also, check your muffler and spark arrest, sometimes if they are clogged, you will have a similar issue.

You probably have a bad hose or a bad hose connection that is sucking mostly air instead of delivering full fuel to the carburetor!

In the middle of the drum is usually a small torx screw... I put pull cord rope inside where the plug goes to stop the piston from moving as I'm unscrewing it..

I had the same problem. If you replace the lines and you get them swapped, it just won't run. Nothing will be damaged. So then just swap them around. There are only two choices. Trial and error worked for me!

Probably needs new fuel lines to/from and in the tank. Have you been using ethanol gas? It eats up the fuel lines on 2 cycle motors. After you get it fixed, use only pure gasoline. I've had to rebuild two of mine so far!

If it has a primer bulb those typically connect to the carburetor at the diaphragm with a return line going to the tank. The larger line is for the carburetor fuel feed from the tank. All lines that are meant to draw fuel from the tank will feature a filter on the end usually inside of the tank.

The symptoms you reported are commonly resolved when the following is checked, then cleaned or replaced:
  • fuel filter - located inside the gas tank
  • Spark plug
  • Spark Arrestor - at muffler. When clogged with carbon build up, the exhaust flow is extremely restricted, and causes problems
  • Carburetor - may need a new rebuild kit
And watch this...

And this one...

Under what conditions does it bog down? When it just idles? Cold or hot? When you give it gas? When you try to cut?

If you haven't changed fuel filter in awhile, do that as well.
