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.
Over time, the spark arrestor can become clogged with soot. If the spark arrestor is clogged, the engine may not start. To unclog the spark arrestor, remove it and clean it with a wire brush. You may also replace the spark arrestor.
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.
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.

If your 2-stroke brushcutter fails to start, the simplest explanation is that there is not enough fuel: in this case you simply need to top it up. A 2-stroke brushcutter engine runs on fuel/oil mixture, which you can buy ready prepared, such as EFCO-Mix Alkilate alkylated mixture in a 5 L can.
If you learn the steps of fuel filter replacement, you can do this fast, economical DIY job next time your vehicle needs a new fuel filter. Although details vary from one vehicle to another, the basic procedure is the same as I have described here. Cost for parts = $15 to $125.
What is the fuel/oil ratio for my product? A 50:1 ratio with 89 through 93 Octane fuel can be used in all ECHO 2-stroke equipment, provided the oil is ISO-L-EGD and JASO M345 FD certified.
Common signs include reduced engine performance, black smoke coming from the exhaust, backfiring, overheating, or hard starting.
One reason why one of these trimmers may die at full throttle is that too much oil is in the gas, which causes poor combustion. Improper operation, including overuse of the choke, can also be responsible. Poor combustion produces carbon deposits that foul the spark plug and exhaust port, making the problem worse.
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.

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.

My blower only runs with 3/4 choke even after warm up.
ANSWER : Look on the carb for 2 screws side by side. where those screws go into the carb, it will be stamped with an “H” and “L”. Open the screw that is next to the “H”, counterclockwise about 1/4 turn at a time with the engine running, that should solve it.

Have a royobi starved for gas
ANSWER : I have always had great luck with echo and stihl trimmers. If you keep up maintenance on them, they always seemed very reliable to me. I have a couple of each and have had them a long while and they still do a good job. Hope this helped and best wishes.

On your current weedwhacker; clean or replace the in-tank fuel filter, clean the spark plug, and clean out the screen at the exhaust port and see if that helps.

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.

Will only develop power (and run somewhat properly) when the choke is engaged about 90%. Starts fine.
ANSWER : Sounds to me as tho you may have a loose carburetor or another part that is letting air into the system. Check all bolts and screws for tightness. Also, you may need to clean the carburetor or put some cleaner in your gas. Not too much, only about a tablespoon, but check the screws/bolts first.
