How to Unflood a String Trimmer
If you flood your car's engine, you often have no recourse but to wait 10 or 20 minutes for the gas to drain from the carburetor before the engine will start, but that isn't necessary with a string trimmer. A simple procedure should get the engine going without any delay at all.
Step 1: Open the Choke
Set the choke to the "off" position. On some models, this position is labeled "run," or it may be denoted by a single vertical line as opposed to two vertical lines for the "choke" position. If your model has a priming bulb, you don't have to worry about the choke but just remember not to press the priming bulb.
Step 2: Hold In the Throttle
Depress the throttle all the way as if you were operating the trimmer at full speed.
Step 3: Quickly Pull the Cord Several Times
Continue holding in the throttle while you pull the starting cord repeatedly several times. Eventually, the motor will sputter, and if you keep pulling, it will eventually turn over. When it does, ease off the throttle until the engine is running smoothly.
Why This Works
When you open the choke and depress the throttle, the engine will draw a small amount of gas from the carburetor and combustion chamber each time you pull the cord. While this gas doesn't get burned, it does get expelled through the exhaust. Eventually, the ratio of gas to air in the carburetor becomes lean enough for the spark to ignite it.
Keep Your Trimmer in Shape
If you're experiencing frequent problems starting your trimmer, simple maintenance can get it back in shape:
Place Chainsaw On a Flat Stable Surface
The first step is to place the chainsaw on a flat stable surface to perform the unflooding procedure.
Remove Spark Plug
The chainsaw’s spark plug will need to be removed from the engine in order to remove excess fuel from the cylinder. Most chainsaws require the operator to remove a top cover to expose the spark plug. Once the cover is removed you will need a chainsaw wrench or a deep socket size 19mm (3/4″) to remove the spark plug.
Remove Air Filter
The air filter will need to be removed next. The air filter is located adjacent to the spark plug under the top cover you removed in the last step. The air filter is normally, depending on your chainsaw’s model number, held in place by snap clips or screws and is very easy to remove.
Set Choke to Off and Pull Starter Rope 20 Times
Now that we have the spark plug and air filter removed from the chainsaw we can now purge the excess fuel from the cylinder. Be sure to wear safety glasses before going further as there is a risk of getting fuel in your eyes in this step.
Dry or Replace Spark Plug and Reinstall
With the excess fuel removed from the chainsaw’s engine, we need to turn our attention to the spark plug. The spark plug will more than likely be wet with gasoline and will need to be cleaned or dried.
Clean or Replace Air Filter and Reinstall
The air filter that was removed earlier will more than likely be dirty or damp with fuel. If this is the case the air filter may be able to be cleaned by gently tapping the filter on a hard surface and blowing lightly with compressed air.
Engage Chainbrake
Now that the saw has been cleared of excess fuel from the engine and the spark plug and air filter have been reinstalled the chainsaw will need to be started.
