20 Most Recent Craftsman 25cc Gas Line Trimmer Questions & Answers

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

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!

For two stroke engines of this capacity the ratio of fuel to two stroke oil is (25:1) 25 fuel to 1 (two stroke) oil. Eg 200 ml of two stroke oil to 5 litres of fuel.

The smaller diameter line (fuel supply) goes from the fuel tank (w/filter) to the carb body. Another larger line (purge line) goes from carb body to the right nipple on the primer bulb. Another large line (return line) goes from the left nipple of the primer bulb into the fuel tank. co0mpleting the purge circuit. This info pertains to my 2006 Craftsman 32cc with Zama carb.

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!

The carb must be cleaned. take the carb off put it on a work bench and pull it apart layer by layer... be careful as there is a spring that will jump out. pull all of the gaskets off and clean behind them. make sure all of the passages are clean. Use brake cleaner from the auto parts store! do not use carb and choke cleaner as the gaskets will instantly expand and be useless. there is also a brass cylinder in the carb you need to remove it and clean it well. There should be a very small hole in the center. put it back together and you should be good to go
