How To Adjust The Carburetor Of Weed Wacker
Carburetors are those kinds of components that should be constantly
maintained after some time. There are instructions given in the manuals in
which it is clearly written that that after how long the carburetor need to be
adjusted again. But the question that comes on to mind here is what does the
adjustment mean and how it could be done?
All Weed eaters require a carburetor adjustment from time to time. Weed
wacker carbs will loose their tune because the adjustment screws may work
themselves loose from vibration, fuel
mixtures may slightly change or you
may change the trimmer head causing
a different load on the engine. The
carburetor settings drastically affect
the performance of your trimmer. All
the weed eater trimmers use a two-
stroke engine where oil is added to the fuel manually at a preset fuel to oil
mixture. To adjust your carburetor you will need to find the two fuel
adjustment screws on the carburetor body. The screws are highlighted as HI
and LO. Simply speaking the HI screw allows the fuel adjustment of the weed
eater at full throttle. Whereas the LO screw allows the fuel adjustment when
the engine is idling.
Follow the listed steps and video tutorial link below to tune your Weed eater
carburetor:
1. Adust both screws clockwise until just tight using the correct tool. This will
be the reference position for adjusting the carburetor.
2. Rotate the HI screw one and a half full turns counter-clockwise.
3. Rotate the LO screw one full turn counter-clockwise.
4. Open the choke by pulling the choke level all the way out or turning it to full.
