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 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.
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.
If your trimmer won`t turn on, especially if it has not been used recently, you may simply have a drained battery. Plug your trimmer into your charger and see if anything happens. Ideally your trimmer will recognize it has been connected to a power source and charge its battery.
Checking the Fuel Mix

The most common problem with a strimmer not starting is that there`s a problem with the fuel mix. Double check that you`ve used 40 parts fresh unleaded petrol to 1 part 2-stroke oil (40:1). Check the petrol you`ve used isn`t stale.

An electric trimmer`s power cord, switch, or motor may fail. A gas trimmer`s engine may be faulty. The air filter or exhaust port may be blocked. The trimmer may need lubrication and cooling fins or air passages may be blocked.
Unless your tool instructions specifically say to store the battery on the charger, be sure to remove it after charging is complete. Overcharging can damage a battery and shorten its life, and not all chargers shut off automatically.
The most likely culprit is a dirty or clogged air filter. Issues with your fuel pump or fuel filter can also cause your engine to idle then die with any throttle. If you have an older car, it could also be a bad carburetor.
The most common reason for the cord refusing to rewind is a broken or worn out recoil spring. This tiny spring hooks onto the pulley and is stretched out when you pull the cord; when you let go the spring is meant to snap back to its original position.
Find the adjustment screws on the front of the carburetor.

There should be two screws on the front of the carburetor, which are used to adjust the air and fuel mixture. These often look like flat-head screws, and you can use a screwdriver to turn them, adjusting the amount of fuel and air mixing in the carb.

The head won,t turn – Craftsman 25cc Gas Line Trimmer
ANSWER : You will need to pull the head off, as it sounds like the cable is off. there should be four bolts/screws, there maybe some in the middle also, gently remove the head(this is the top of the trimmer where the pull cord is, once you have it separated you can turn the cable by hand and the line feeder should rotate, if it does then look inside the head and make sure it is still square and not rounded. or you can pull the line feeder off and pull the cord and see if the cable rotates, whichever you feel comfortable with trying. Good Luck Tim

ANSWER : It may be that the drive shaft is broken, or not engaged to the engine. Make sure the trimmer attachment is locked all the way onto the shaft coming from the engine. If it still doesn’t work, check by seeing if any of the other attachments work when you put them on. If they do, you know the drive shaft in the trimmer attachment is probably broken.
