Experienced gardeners share their insights in answering this question :
Soft seat the set screw and back out 1 1/2 turns. This is the standard to start adjustments from. Set the low speed one first, then the high. With it running and warm, couple of minutes, turn in until starts to run rough, then turn out til is starts to run rough, then set in the middle of those two points. Go to the other and repeat procedure.
How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
If your carburettor has a main jet adjustment screw at the base of the float bowl, turn the screw clockwise until you feel it just touch the seat inside the emulsion tube. Then, turn the screw counterclockwise 1 to 1-1/2 turns. Replace the air cleaner assembly and start the engine for final carburettor adjustments.
Tip: The factory position for most air fuel mixture screws is usually between 1.5 and 2.5 turns out from being screwed all the way in. If you ever want to start fresh, turn the screw clockwise until it is lightly seated, then back it out about 2 turns.
If your trimmer engine idles, but stalls on throttle, check the following parts: the gasket, primer bulb, fuel filter, air filter, fuel vent, fuel line, and carburetor. The repair and symptom guide will help you better identify the part needed to be replaced and how.
This method involves looking at the base of the spark plug insulator (white part of the plug) for a slight coloring on the insulator just above where the insulator comes through the steel case. If the mixture is too lean, it will leave no color, while a rich mixture will cause the fuel ring to become more prominent.
If your trimmer engine idles, but stalls on throttle, check the following parts: the gasket, primer bulb, fuel filter, air filter, fuel vent, fuel line, and carburetor. The repair and symptom guide will help you better identify the part needed to be replaced and how.
They are typically labeled L (low speed jet), H (high speed jet), and I (idler jet). Your saw may be labeled differently (in the photos in the Gallery below, the idler jet is labeled “S”), but you`ll have three screws that correspond to these descriptions.
With the engine at normal operating temperature, adjust all the idle mixture screws until the engine idles at the desired rpm with the highest manifold vacuum. Once that`s achieved, lean the air-fuel mixture by adjusting the mixture screw clockwise a tiny amount for each adjustment screw.
