How do you adjust H and L screws on a carburetor?
Set the idle speed screw(not L or H) so it is just able to idle by itself. This screw will have a “stop” it rests against. Now turn the L screw out until in decreases in rpm and then back in(very slowly) until it is at peak rpm. Adjust the H screw once more as above and it should be a very serviceable 2 stroke.

How do you adjust a carburetor on a small engine?

Why does my gas trimmer keeps stalling?
A clogged fuel filter is most commonly caused by leaving fuel in the string trimmer for a long period of time. This sticky fuel can clog up the fuel filter and cause the engine to stall. If old fuel was left in the string trimmer, drain the old fuel from the fuel tank and replace the fuel filter.
How do you adjust a high and low carburetor?
Locate the two fuel-adjustment screws on the side of the carburetor. One will be labeled “Hi” and the other “Lo.” The “Hi” screw regulates the engine at full throttle and the “Lo” regulates the fuel when the engine is idling.
What do H and L screws do carburetor?
Look for the carburetor adjustment screws either near the air filter or under the spark plug. There are three of them, marked “H,” “L” and “I” or “LA,” depending on the model. They are the high-speed, low-speed and idle adjustments respectively.
How do you lean out a carb at idle?
The first thing to do is not set up the idle speed, but to set the Idle mixture screw to lean best idle setting. First, turn in the mixture screw until the engine dies or runs worse, then back out the screw (recommend turning ¼ to ½ turn at a time). The engine should pick up speed and begin to smooth out.
