Listen carefully and follow these steps
1. Walk outside and grab the trimmer
2. Open the lid of the garbage can
3. Place POS in the garbage can
4. Get in vehicle
5. Drive to a Stihl dealer
6. Buy a new trimmer

Sorry I could not resist, those things are not worth your time trying to repair.

Are you sure you are turning the idle adjustment screw and not the fuel mixture adjusting screw ? Is that a Walbro carb with single mixture adjusting screw or does it have 2 screws;one for low speed adjustment and one for high speed adjustment ? The idle speed screw adjusts the position of the throttle plate/butter-fly .

According to manual i believe one screw with spring in between is the one for idle speed adjustment screw (that's the one i had rotated so far).
Also since you mentioned underneath this screw there is small two round section and inside there are two screws but not sure what those are for (looks like it may need different tool to turn that).

Weedeater is a Poulan product and your model shows it came with both a Zama C1U, W18 and a Walbro WY669. Look at both of their websites for troubleshooting and repair manuals.

I'm with Mowerknower, they're hardly worth the effort.

Besides the idle bolt there are 2 needle adjust, 1 with a L and the other one with H, try adjusting the L=low speed, left for more rich, or turn right for lean, in combination with idle you'll get it working right. Also check spark plug and air filter.

I google the model and brand and end it up with walbro carbs. check it out.

There is nothing better then a commercial grade trimmer, but if this one still has life in it, use it 'til there is no hope, I have a weed eater bought on 2002 and it is still working, starts from first pull model BC 2400.
