Has the pull string on your weed eater become jammed? In that case, you won’t be able to start up the weed eater.
I have personally encountered such a problem numerous times, which led me to type in the words - “why can’t I pull the string on my weed eater?” into my Google search bar.
Meaning, I obviously did some digging into this problem, and I have presented my research in this brief article. Thus, if you have a similar issue, keep on reading to know how you can fix it.
Let’s get going!
There can be different reasons as to why you’re unable to pull the string on your weed eater. I have discussed the most common ones in the list below.
If you use your weed eater a lot, then it is quite natural for the pull string to break with repeated usage. In some cases, the broken string may be entirely separated from the weed eater. Or the broken cord may get tangled with some internal engine components, making it hard to pull.
An intact cord may become stuck if it gets tangled with some other component inside the engine. It can also happen if a foreign object gets lodged inside the pulling mechanism. Or, if the string becomes loose, it can get entangled with itself and form knots that can prevent you from pulling it.
Typically, the string is housed in the recoil mechanism of the weed eater. It uses a spring to retract the pull cord back inside the weed eater. So, if you have a fault in the retraction mechanism, such as a broken recoil spring, then you will have difficulty pulling the string.
In this regard, the string will not be pulled back into the weed eater either, which can be pretty problematic.
The engine may resist ignition if there is a buildup of exhaust residues or bad fuel in the weed eater engine. This is achieved by keeping the pistons in the combustion chamber closed. Thus, you will not be able to pull the string, which typically controls the movement of these pistons.
This is not an issue with the string, it is more of a design safeguard that protects your weed eater engine from damage.
Once you determine the reason, you will need to troubleshoot it accordingly. In case of residue buildup or bad fuel, your best bet is to clear the engine and replace the oil. And if the string is stuck, you can get it free by tugging it a little harder than usual.
However, if tugging doesn’t work, or there is another reason why you can’t pull it, you can follow the steps below.
First off, remove the shaft of the trimmer from the engine block by removing any screws holding them together. Make sure the weed eater is off before you do this. Subsequently, disconnect the wires connecting different components in the engine block.
Using a screwdriver, unscrew the spark plug and clutch plates. Make sure to bind the pistons with a cloth to prevent their movement. Also, make sure to remove the clutch drum to access the engine housing.
Unscrew the two halves of the engine housing to expose the motor and the recoil mechanism below it.
Now that you can see the recoil mechanism, you can service it accordingly. If the string or spring is broken, replace them with new ones. Or, if there is something lodged inside, remove it, and wind up the string in the recoil mechanism pulley.
Once the problem is solved, reassemble the different components, such as the engine housing, spark plug clutch plate, and others like they were before.
So, now you know why you can’t pull the string on your weed eater.
I have also provided a process that you can follow to fix this problem on your own. However, if you are not so experienced in these things, you can seek expert help or consult the manual of your weed eater.
With that, this brief guide has come to an end. So, until next time, I bid you farewell.
