When your line trimmer is difficult to start, here are a few easy steps to try before you start tearing it apart.
Make sure the on/off switch is set to on.
Make sure the fuel tank has clean, fresh gas in it.
It's possible the engine has flooded with fuel. To fix this, place the choke lever in the off position, hold the throttle trigger fully open and pull the starter rope 5 or 6 times to clear the engine carburetor of excess fuel.
On models that have a primer bulb, press and release the bulb two times. This removes air in the fuel lines and puts fuel into the carburetor.
Activate the choke by moving the lever to the full choke position and pull the starter rope 3 or 4 times.
If the engine has not started, move the choke lever to half choke and pull the starter rope, 6 times maximum.
If the engine still won't start, the problem could be a faulty spark plug, fuel line or carburetor. See our DIY page for repair procedures for these symptoms.
