    Thanks for you response. To change the air filter i assume you have to remove the back 1/2 of the plastic housing around the engine. It has, I believe thy are called, torque screws holding it in place. Alsi, i did look at the spark plug already. it did not appear fouled. Should I change it anyway? John

You need to do a couple of things to get your trimmer back on track. First of all pour out the old gasoline and get rid of it. Then remove the spark plug and go to an auto parts store and get a new one just like the old. If you have your manual, check to see what the recommended spark plug gap is gap it to that specification.

Finally remove the air filter and clean it or replace it as necessary.

Once that is all done, but some new, fresh gasoline. Then put in the new plug and the new gas and u will be good to go. please rate this answer as a FixYa cause it is.

Why wont my craftsman 25cc start


99% of the time its a carb or fuel problem. Always run premium fuel and store the machine in a cool place less than 100 F
Might can put a drop or two of fuel down the carb and revive.

My 7-year old 25cc Craftsman line trimmer began surging during use, would bog down when given throttle, then would completely die, became hard-starting, and now doesn't start and run at all. Acts like...


A new fuel filter with new fuel lines and a rebuild kit for the carburetor should do it. You may even be able to get away with just the gasket and diaphragm kit for the carburetor. It is cheaper than the complete rebuild kit if you choose. Run synthetic oil and these things will last a good long while.

Craftsman 25cc Gas Line Trimmer dies when giving throttle. It starts up and runs in the "Start" setting, then dies as soon as you give it gas. I replaced the carburetor...it ran great immediately after...


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.

Runs on choke a little


sounds like the carburetor has gummed up a bit, and may need adjustments - or, the fuel pickup in the tank has come loose [i.e.: deteriorated fuel lines] - also, make sure your gas mix is FRESH. if your gas mix is more than 2 months old, dump it

Craftsman 17" 25cc Trimmer...pull cord stuck


it's doubtful that bad gas caused this, it sounds like the cord was back-lashed and partially came off the recoil pulley. Remove the recoil cover and ensure the cord is all on the pulley, make sure the rewind mechanism works smoothly before re-installing.

Trimmer starts immediately, then stops


How old is the trimmer? If still under warranty, Sears can fix this. If not, then my experience has been the problem is a bad coil. This is due to heat build up. When the coil gets hot, it shorts out.
