Adjusting the carburator on a craftsman 25cc line trimmer

You might want to Google the model number for a service manual or contact a sears service parts center for help.

need to adjust the high sscrew. i do mine in 1/4 turns. start machine, full throttle, adjust the h(high) til it clears up.i would start by turning 1/4 counterclock wise, just remember to keep track, in case it runs worse, the put it back to orig. then try the other way. but i suggest 1/4 turn at a time

example... think of a clock when turning screw. straight up and down, 12oc, 1/4 turn will be 3oc, another 1/4 will be 6oc, and so on. hope it helps!

The low side carburetor adjustment screw needs to be turned counter-clockwise. Start by turning it 1/4 turn then test run. If your carb has plastic locks on the screws, they will have to be removed first. Most modern carbs require a special tool to adjust the jets. The tool can usually be purchased from your local repair shop.

Just about any 2-cycle can be started by bottoming out the pins fully. (All in, clockwise rotation) Then, back them out 2 and a half turns. Remember, this will get it to start! Getting it to RUN will take some tweaking. If it idles, no worries, the idle is just there to keep it warm. Concentrate on fiddling with your high speed screw after the engine has idled up to operating temp for at least 3 minutes, and when placed into LOAD. NEVER adjust by sound or feel with NO LOAD. Too easy to get them too lean and pop their little heads off. ;D

The primer bulb needs to be replaced. It is introducing air to the system and not allow fuel to flow. Replace it and check the fuel lines while you are at it.

Good Day

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

the tool is Poulan Part Number 530 035560 and can be purchased at http://cgi.ebay.com/POULAN-CRAFTSMAN-HUSKY-CARBURETOR-ADJUSTING-TOOL---NEW_W0QQitemZ280351588986QQcmdZViewItem or just google the part number and you will find it.

If the adjustment screw is star shaped you will need torque bits. You can get them at hardware store or auto store

The gas take up line is disconnected or is broken. I have the same problem and need to find a diagram to fux it.

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.
