How do i perform weedeater xt125kt carburetor adjustment?

Answer 1

There are two screws H, and L.

Bottom out both screws gently.
Turn out both screws 1 and 1\2 turns. (initial setting)

Adjust the L. (low) to attain good idle.
Now, give it full throttle and adjust the "H" untill you attain a somewhat stumbling high speed. NOT REALY FAST.
