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 the engine is not revving up and cuts out before you reach higher revs then you need to do the following checks: Fuel: Make sure it is fresh and correctly mixed (see `Starting Issues`). Air filter: Make sure it is clean and unclogged. Fuel cap: Make sure it`s hand-tight.
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.
When your trimmer starts and runs on choke, it could be because the check valve in the gas cap is clogged. Start the trimmer and gently unscrew the gas cap halfway off. Turn the choke off and assess. If the engine is still running, that means the gas cap may be the culprit.
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 causes are problems in the ignition (for example, a bad ignition coil) or fuel system (for example, a clogged fuel filter). However, the source may also be a mechanical fault (for example, a leaking valve) or faulty components in other systems.
Basically, the gas is coming out of the gas pump at a pressure that is too fast for the car to take in. If the air vapors do not get out fast enough and the tube gets covered by gasoline, a vacuum forms inside the nozzle which will automatically switch off the flow of gas into your tank.
First prime the carburetor, by pressing the priming bulb five time. This ensures there is enough fuel into the engine to start the engine. Activate the choke and pull the starter cord until the engine ignites. Once the engine has stopped deactivate the choke and pull the starter cord again until the engine starts.
Check the following: Clogged muffler, clogged exhaust port, fuel restrictions, low compression, poor ignition spark, too much oil in gas or improper air/fuel mixture in carburetor. . Clean carburetor jets and air filter. Check clutch gear wheel for worn or greasy clutch pads.
It`s simply 40 parts of fresh, unleaded fuel with 1 part of semi-synthetic 2 stroke oil.
This ensures there is enough fuel into the engine to start the engine. Activate the choke and pull the starter cord until the engine ignites. Once the engine has stopped deactivate the choke and pull the starter cord again until the engine starts.
Usually this is the result of the cutting head being taken too close to objects, e.g. garden stones, paving edges, walls etc. The cutting line must be allowed to rotate freely and the correct diameter and type of line should be used.
The clutch engages the clutch pads to spin the trimmer head. If the clutch assembly is defective, the clutch will not disengage the clutch pads, and the trimmer head will continue to spin, even at low speeds. If the clutch is defective, replace it. (Note: some string trimmers do not have a clutch.

Often it’s the easiest thing that stump us. Try changing the spark plug first. Sometimes a spark plug just won’t fire under load, i.e., while it’s in the cylinder but will spark if you have it removed. There are checkers for this, but it’s a lot less expensive to just replace the spark plug. Do that first and let me know.
