This is a genuine OEM replacement part, it is sold individually. It is used on specific Gas Trimmers. The purpose of this part is to mix air and gas before the fuel mix goes to the engine. If the engine won't start and the tank is full of fresh fuel, test the carburetor by removing the air filter and pouring about a teaspoon of fuel into the carburetor. Pull the starter rope. If the engine starts and then quickly dies, the carburetor is likely the problem.

Hi Francisco,
Glad to here from you. The carburetor for this model is sold as a complete unit, there is no diagram listed for it. If there is an issue with the carburetor it will need to be replaced. We would recommend checking the videos on our website for information, if you need to take it part. Here is a link to the videos, https://www.ereplacementparts.com/repair-center/lawn-equipment/videos/?search_string=carburetor. If you have any questions, please let us know. We look forward to hearing from you!

Basically, remove the carburetor assembly, existing fuel lines and fuel filter. Screw the new carburetor (bolts) onto its mount. Measure the length of the existing fuel lines and cut the new ones to that length(s). Cut the ends of the new fuel lines at a 45 degree angle so they can be twisted into the fuel tank without damage. After inserting the lines, hook them back out of the fuel tank with a piece of curved wire, re-cut them straight across and twist on the new fuel filter. After inserting the lines back into the fuel tank, and connecting them to the carburetor, add fuel, pump up the carburetor and pull start the engine. After it warms up, adjust the carburetor idle speed screw and it's all done. It works like new.

These are the steps i used... Remove fuel lines from carburetor note position of each. Open up cover of air box. Remove air filter. Remove two screws with Allen wrench. Remove air box. Slighty remove carburetor and unhook throttle cable linkage noting the way it hooks up. Remove carburetor. Make sure old gasket doesn't stick to carburetor adapter. Remove two screws and remove carburetor adapter. Take carburetor adapter, air box, and air box cover and clean with toothbrush and dishwash liquid. Dry thoroughly. Take a q-tip dip in cleaner and clean around cylinder where adapter fits. Push screws through carburetor adapter and put new gasket on screws pushing it on adapter so it lines up perfectly. Tighten adapter on cylinder. Push screws through air box, new carburetor, and place new gasket on screws against carburetor so gasket lines up perfectly. Install throttle linkage cable to carburetor. Tighten screws back down. Clean air filter, or replace then install air box cover. Hook fuel lines back up in proper position. Always, ALWAYS use non-ethanol gas in your weed eater with proper oil mixture. My Poulan weed eater is 13 years old and this is the first time I habe replaced anything on it.

Removed filter and carburetor. Next I removed the air and gas line from tank after draining the gas. Removed gas tank. I then ran the new fuel lines. It is a tight fit to reinsert the new lines. I ran a small diameter wire through the lines ,folded it over the end that would be inserted at the Carb. and pulled the new lines into the tank. After reinstalling the gas tank, I replaced the spark plug. Securing the new carburetor and reattaching new gas lines. I filled gas tank with new premixed 50:1 fuel. Pumped the fuel bulb, gave two pulls on the pull rope. The unit started right up and ran so smooth. This is about the 4th gas powered equipment that I have ordered parts from ereplacement that has fixed each one of them. It won't be the last time. Thanks eReplacement Parts.

I tested the carb with starter spray by spraying some into the carb, and it started briefly so I knew the carb was not sending air and fuel to the cylinder. Rather that rebuilding the carb it was easier just to replace it.

Parts Used
This carburetor did not offer a rebuild kit, so a new carburetor was ordered. Replaced the carburetor and the two fuel lines (supply and return lines). Two screws hold the carburetor and air breather assembly in place. Removed breather and carburetor and disconnected the throttle cable. Connected the throttle cable to the new carburetor (do not forget to use the rubber gasket that sits between the carburetor and cylinder). Installed the screws that hold the carburetor and air breather, installed the breather element. Also replaced the supply and return fuel lines from the gas tank to the carburetor. HINT for routing the fuel line through the gas tank: Make an angled cut, with a razor knife, to make a point on the fuel line. Use a little two cycle oil and wipe down the fuel lines about 3 to 5 inches from the point. Push the fuel line point into the hole of the gas tank. Using a pair of angled needle nose pliers, reach into the gas tank through the fill hole, grab the fuel line and pull the amount of fuel line needed inside the tank, cut off the point, install the furl filter on the supply line and place back into the tank. Follow the same procedure for the return fuel line.
