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 :

A clogged carburetor is most commonly caused by leaving fuel in the string trimmer for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to stall.
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.
Over time, the spark arrestor can become clogged with soot. If the spark arrestor is clogged, the edger may stall or run roughly. To unclog the spark arrestor, remove it and clean it with a wire brush. You can also replace the spark arrestor.
The air filter or exhaust port may be blocked. The trimmer may need lubrication and cooling fins or air passages may be blocked. A cordless trimmer`s battery or charger may be faulty.
Air filter

Once blocked with dust and debris, it cannot supply the required amount of oxygen to your trimmer` engine resulting in power loss. Find the air filter, take out this component, clean and reassemble it. Replace the part if you cannot reuse it. Follow this step regularly to avoid any problems in the future.

If the engine will idle but dies at full throttle the main jet in the carburetor may be plugged. You can repair a plugged main jet by cleaning it, replacing the jet, or replacing the carburetor. If you choose to clean or replace the main jet, you will also want to clean the rest of the carburetor.
Sometimes the spark arrestor screen can become clogged up itself. Common symptoms include lack of power, especially under load; poor acceleration; engine won`t come up to full RPM; and higher than normal “spit back” through the carburetor.
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.
If the drive shaft is broken, the string trimmer head won`t spin. The drive shaft is not repairable—if the drive shaft is broken, you must replace it. Need help finding your model number? If the threads on the drive shaft are stripped, the trimmer head will not stay on the shaft.

The fuel can dry in the carby and stop the unit from starting.

My ryobi bc30 starts but will not stay running. I only see one screw for the carb but it dont seem like it adjusts anything. I have turned the screw all the way in and out doesnt fix anything. i do not have an air filter in it. could that be the problem? I am also using a gas mix that is the same for my chainsaw. could that be the problem? getting very irritated with it and ready to just toss it in the trash.
ANSWER : Hi there,
The problem is that the diaphame in the carb. is worn-out and you need to replace that.It is very important that you run your machine with a air filter as the small particals can damage the diaphrame.Also remember that the older machines run on a mix of 30 to 1 and the new machines run on a 25 to 1 mix.
Trust that this will solve your problem
Regards
Edu

Ryobi 18v One+ battery won’t hold a charge. I have two of them and neither one will hold the charge. The charger is the Ryobi 18v charger plus. I have the same problem. As soon as I put the battery in the charger (even if it is dead) the “charging”, and the “fully charged” lights both come on. Even if I leave it for a day the battery will not charge.
ANSWER : If it’s both of them then i am thinking you have a faulty charger. i have seen mine do that, i got a new charger and it worked properly.
