How do I reinstall a pull cord on my line trimmer?


Remove the trigger housing on the drive shaft by removing the 4 screws and separating the housing. Make note of how the trigger and the throttle cable mount in the housing.

Remove the clamp on the clutch cover and remove the drive shaft and housing from the clutch. (it pulls out).

Remove the screws from the clutch cover and remove the cover.

To remove the clutch drum, remove the small torx head bolt in the center of the drum. The clutch drum will slide off the engine shaft. If the engine shaft turns when you are removing the screw, remove the spark plug and fill the cylinder with small clean rope. The rope will jam the piston and stop the engine from turning.

Remove the screws holding the fan housing to the engine and remove the fan housing. The rope and the starter pulley are inside the fan housing.

Be very careful removing the starter pulley and spring. The spring will unwind violently if it is released.

As you install the rope on the pulley, turn the pulley. Let the turning of the pulley wind the rope and it will load the spring so it will retract.

Not sure what parts to get for a craftsman weed trimmer model 316791810


Thank you for submitting a question to Manage My Life.

I am including an image of the parts below. Make sure the part I marked green is tight. This is a clamp and should have an anti-rotation screw that goes into the shaft, through the part I marked in yellow. I assume the part I marked in red is the part that is falling off.

Here is a link that you may use to view the parts list diagram or purchase any parts needed for your trimmer; Sears Parts Direct .

I hope this is helpful, and if I may be of further assistance please include more details in a reply to this post.

What causes the compression in my gas trimmer to be so high I cannot pull it?


Thank you for your question on the trimmer not starting after it has been shut off.

If you have to wipe the spark plug off to get it to start it sounds like it is flooding and the spark plug is wet with fuel.

With two much fuel in the cylinder it would create high compression because of too much liquid fuel in the cylinder chamber.

It sounds like the diaphragm in the carburetor is stiff and is holding the needle valve open a little and flooding the cylinder.

I would suggest installing a carburetor repair kit but I cannot find one for this carburetor.

They only show a complete carburetor assembly.

Carburetor replacement for model 316.791810 .

Thank you.
