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 :
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 carburetor or fuel filter might be clogged.
First, check the carburetor to see what has happened. If it`s clogged, there are three options: clean the carburetor, rebuild it, or replace it entirely. If a clogged fuel filter is the source of the issue, you`ll likely need to replace it.
If your carburetor is clogged, it can cause your leaf blower`s engine to die when the choke is disengaged. You can disassemble it, clean it, and replace individual parts with a carb kit. Once your carburetor has been unclogged, cleaned, and re-assembled using the carb kit, the engine should run with the choke off.
If your blower is having a difficult time starting, then you may be dealing with a carburetor issue. The carburetor`s job is to ensure the proper mix of fuel and air is directed to the blower`s engine. As mentioned, the carburetor can become clogged, making it difficult for fuel and air to enter the engine.
This is caused by a rich/lean cycle at idle. As the motor leans out the RPM`s increase and richen up the motor, when the motor richens the RPM`s decrease and the motor leans out again. This continual cycle is known as “blower surge”.
First remove and reinsert the battery to ensure that it`s seated properly in the Blower. If this doesn`t work, check the battery charge level by pushing the battery indicator button. If the battery is low, stop and charge the battery before use.
Frequent sputtering: If your leaf blower misfires or sputters when in use, a partially clogged fuel filter is usually the culprit. Strong odors: If your leaf blower emits strong-smelling fume, that can be another sure sign of a partially clogged or dirty fuel filter.
If your boat is equipped with a power ventilation system (exhaust blower), turn it on for at least four minutes before starting your engine. This will help eliminate fuel vapors in the bilge.
Many times this is caused by a plugged vent in the gas cap. Try running it and unscrew the fuel cap part way to see if venting the tank will allow it to run without the choke. If so, then clean the cap with hot water and dish soap or replace the cap with a new one.
There are many different reasons why a leaf blower may fail to start, including stale fuel, engine flooding, dirty air filters, faulty spark plugs, defective batteries, blown fuses, and contact issues of the power switch.
Replace the leaf blower carburetor
If the engine starts and then sputters, or doesn`t start at all due to lack of fuel, you might need to replace carburetor.
Defective spark plug – Due to carbon build-up or a weakened electrode, a spark plug will degrade over time and be unable to ignite the compressed fuel and air inside the engine`s combustion chamber to start or run the engine.
The easiest way to tell if your engine is flooded with gas is to remove the spark plug. If it`s wet, it`s flooded and you`ll need to let the cylinder dry out before trying to restart. Compressed air can help speed up the process.
When trying to start a flooded engine, the end goal is to re-establish the fuel-air balance in your vehicle. To do so, simply open the hood of the car and let the excess of fuel evaporate. After waiting for some minutes, try starting your car again, keeping your foot away from the gas pedal.
3. Surging and Lagging. Another good indication that your spark plugs are dirty or worn is if your vehicle experiences surges of speed, resulting in a jerking acceleration. These surges occur because your spark plugs are not igniting the fuel in your engine at the proper rate, resulting in an uneven speed.
The fuel filter might be clogged. A clogged fuel filter is most commonly caused by leaving old fuel in the leaf blower. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog the fuel filter and cause the engine to stall.
This cordless leaf blower has a wide tube with a useful plastic notch at the base and the battery has a helpful indicator and a run time of 15 to 20 minutes. It`s compatible with over 150 tools in the Ryobi ONE+ System, it comes with a three-year warranty.
A plugged or improperly adjusted carburetor can cause your leaf blower to start, but then immediately die. Over time, especially if fuel has been left in the leaf blower for a long period, some of the fuel will evaporate and you will be left with a thick, sticky substance that can ultimately clog the carburetor.
A clogged fuel filter causes low fuel pressure that results in a lean fuel condition and engine misfire. This can result in poor fuel mileage, rough idling and possibly cause the check engine light to come on. Once that light is on, it`s time for a trip to the repair shop.

Started PB620-ST yesterday with some difficulty. However, ran until fuel empty. Refueled today, but will not start. Spark at plug ok. Fuel flowing, but seems to overflow into air filter compartment. Does not seem to “fire” at all.
ANSWER : Sounds like your flooding the engine; I did the same thing. Wait a while to let the gas drain back to the tank. Use your primer bulb once and your choke for only ONE pull; then shut off the choke. Pull start without the choke 2-3 times and it should start.

ANSWER : Hello
Does it use a fuel and oil mixture?You probably did that.

Try removing the spark plug and cleaning it with a wire brush or some emery cloth.Make sure you have spark by connecting the plug wire and resting the plug on the metal motor block.
Do not hold the plug in your hand ,if you have no spark you may have a bad magneto.

Ran last year, won’t start this year. Changed fuel and replaced spark plug. Checked spark and attempted to start with battery and tried with pull cord but no start. pulled plug and it had fuel on it so i cleaned it let it sit an hour and tried again, no start. any suggestions?
ANSWER : It might have tipped over on its side. Look at the air filter, if you see oil or gas on the filter then you might have to remove and clean the carburetor. I would start by cleaning/replacing the air filter and trying it again. If its getting fuel and the spark plug works then the only other side of the fire triangle is air.
