Question about Husqvarna 28cc Gas Line Trimmer

1 Answer

My weed eater will not idle. When I removed my finger from the throttle it slows down and dies. It will start under half choke and run 1/2 throttle to wide open, but will not idle.

Sounds like you will need to clean your carburetor.
Be sure to use compressed air to blow out all the fuel and air passages.
Be careful when blowing out the passages because there are sometimes small rubber type seats in the bottom of some of the passages.
Sometimes you can get by with priming the carburetor a few times, and letting it run a few times like that and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.
Keep in mind that the float for the carburetor must be level when you go to reassemble the carburetor.
If the mower/weedeater is over a couple years old, then I also recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.
When you clean your carburetor and remove the jet screws, You will first seat the jet screws and count the number of turns it takes to seat the jets from their original position.
That way when you go to put the jets back in, you know how many turns they were in/out.

Starting procedure


Terry: According to eHow.com:

"
  • Put on a pair of safety glasses. Remove the fuel cap from the Weed Eater and set it aside. Fill the fuel tank with unleaded gasoline that has been mixed with quality 2-stroke oil in a 40:1 ratio. Replace the fuel cap.
  • Move the Weed Eater to a safe place and lay it flat on the ground. Depress the fuel bulb located beneath the carburetor approximately six times to prime the engine. Press it slowly so that fuel has adequate time to traverse the fuel line.
  • Slide the handlebar-mounted engine "On/Stop" switch to the "On" position. Slide the choke lever beneath the fuel tank to the "Full" position.
  • Depress the "Throttle Lock" lever located beside the engine "On/Stop" switch. Keeping the lever depressed, squeeze the throttle trigger. Release the throttle lock. This sequence holds the trigger in the depressed position, which aids in starting the Weed Eater.
  • Roll the Weed Eater so that it is resting on the engine and the trimmer head shield only. This will allow the spinning trimmer head to avoid contact with the ground. Brace the Weed Eater by holding it to the ground with one hand. Using your other hand, pull the starter rope quickly until the engine begins to run. Do not pull the rope more than a dozen times. If it fails to start by then, squeeze the throttle trigger and continue to pull until the engine starts.
  • Allow the Weed Eater to warm up for about 15 seconds, then slide the choke lever to the "Off" position. Let the trimmer run for another minute without touching the throttle lever. After the Weed Eater has warmed up, squeeze the throttle trigger once to disengage the throttle lock. The trimmer is now operational.

    What is the proper way to adjust the high low carburetor setting on a Poulan Pro weed eater


    Both should be set at 1 and a half turns out to start. Turning the screws out will richen. Turning in will lean. If its hard to start or boggs/ dies when you throttle then its lean- turn the low out another half turn. If it revs up for a minute then slows down richen up the high. At full throttle you still want to hear a bit of a cackle- adjust the high

    Why won't my FeatherLite FL-20C weed eater will not stay running when I put it in full choke. What could be wrong?


    It should run ok after warming up. After starting it, let it run for a minute or so and then try gradually opening the choke. You might try increasing the throttle setting at the same time. After the motor is hot, if you have to have the throttle setting increased in order to keep it running it means the idle setting needs to be increased, usually by turning a screw to keep the fuel valve from closing so much, or that there is a problem with the fuel flow......like a clogged jet or fuel passage in the carb.

    Weed Eater Problems


    If it runs with the choke closed then it's not getting enough gas. Check the gas filter on the end of the gas line in the gas tank. Remove the gas cap and using a piece of wire with a hook on the end, reach in the tank and pull the gas line out through the opening. Check the filter on the end of it. You could also have a burst-ed diaphragm in the carburetor. This sucks the gas from the tank to the carb. If that's the case a new weed eater may be in order unless you can find someone with the parts to repair it. Also check the gas lines for leaks or breaks, 2 of them.
