How to Fix a Gas Weed Eater That Stopped Spinning

Shut down the Weed Eater's gas engine and wait for the engine to cool off for a few minutes. Unhook or unscrew, depending on Weed Eater model, the cover to the head. Take the head cover off.

Slide the spool, with cutting line, out of the head. Wipe off the area inside and around the cutting head. Wipe off the cover and spool. Check for damage, such as cracks or dents, to the cutting head and cover.

Check the cutting line for any tangles and make sure it's not too tightly wound onto the spool. Pull the cutting line off the spool and rewind, evenly and uniformly, the cutting line if necessary. Check the area around the head and gearbox for any clumps of long grasses. Cut off any weeds or stuck grasses if necessary.

Unscrew the control handle on the boom shaft and separate the two halves. Make sure the throttle cable is connected to the throttle. Make sure the spring inside the throttle is connected to the trigger.

Reattach the throttle cable and spring, if necessary, using the needle-nosed pliers. Check to make sure the throttle cable is attached to the Z-fitting on the carburetor arm, located, on the Weed Eater, in between the air filter box and the engine.
