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.
The trimmer can sputter and stall if it isn`t getting enough fuel, and that can happen simply because the fuel filter is dirty. Fuel filters are inexpensive, and it`s more practical to replace a dirty one than it is to try to clean it. On most models, it`s in the gas tank or on the cap.
As with plug fouling, too much oil in the gasoline, inferior oil, a dirty air filter and/or continued operation at less than full throttle will plug the screen with carbon deposits. This prevents exhaust gas flow, which leads to power loss.
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 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.
What is Bogging? When a dirt bike bogs, it simply means it`s not getting enough fuel and the engine sputters or stalls at full throttle. There are two common types of bogging: lean bog and rich bog, distinguishable by how the bike sounds when you throttle.
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.
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.

Use a Den Tek Brush,(http://www.drugstore.com/products/prod.asp?pid=165357&catid=1152), to clean the small portals in the carb. Make sure the small screen is free of debris. Reassemble and start.If neither one of these solutions work then you will need to buy a carb. kit and replace all appropriate parts.Jim

Only runs with choke on
ANSWER : Sounds like some of the TINY passages [called “galleries”] inside the carburetor have become clogged or partially clogged with fuel residue called “gum” or “varnish.”

Go to your local auto parts store and describe the problem to them, and ask for a solvent “kit” to unclog the carb.

There are a couple of brands, but generally they require that you empty the “old” stale fuel from the tank, add their solvent, crank the engine a few times to get the cleaner into the carb, allow to stand for a few days, add fresh gas and start.
