When my weedeater excaliber starts it runs fine but as soon as I give it gas it bogs down. Acts as though its starving for gas. The fuel filter had come off and I put it back on. The fuel lines are still pliable although when I took the handle apart I found a slight kink in the fuel return line which to the best of my knowledge shouldn't effect how it runs although I could be wrong. Never have touched carb settings.Should I clean carb good or try adjusting carb. Thought maybe that little screen in the muffler should be replaced. Any help would be greatly appreciated. Thanks in advance.

Do you mean it simply wont accelerate?
Screw both H & L fully in, then 2 full turns out will give you an approx factory setting.
From there start her up, throttle fully open turn the H screw clockwise until she is revving at max then give her about 1/8th turn more, this will drop the revs slighty but give you better torque when it hits the green stuff.
L adjustment, easy, just move the screw until its going hard again, then it will be a case of moving the idle screw so the head isnt spinning.
This should give you a a fairly decent set up moving from idle to max without any bogging.
Hope Ive not confused you.

PS if your machine still has the plastic caps on the H and L screws cut them off, they are only there for fuel emission standards when it left the factory, they are more of a nuisance then anything and no real carb adjustment can take place with them on. Removing them should not effect warranty, however if the machine is still new then double check.

I gave this answer to someone else, Im almost certain this will apply to your machine.
