Q:

Craftsman Mower Model 917.378980 Starter Pull Cord issue

A:

The pull cord on the Craftsman mower should not stop halfway when you pull it out. Below are some links that may help to determine if you would like to replace the starter rope yourself or have a qualified technician do it.

Anna, do you know what would cause it to do that 1 out of 5 times on average. Once it starts, it runs like a champ.

Thank you for your question.

I am sorry you are having a problem with the mower. I don�t think the starter is the problem. The starter is nothing more than a pulley, rope, and spring. When you pull the cord, the pawls come out and engage the flywheel cup to turn the engine over. Usually when we encounter the problem you are having, it is because of a partially sheared flywheel key. A partially sheared key will cause the engine to kick back when pulling the rope. When you do not expect it, the force of the kick back will rip the pull rope out of your hands. To check the flywheel key you will need to remove the cover on the top of the engine. Then remove the starter housing assembly. You should see the flywheel now. Remove the nut and the starter cup from the crankshaft. Once that is removed, you should be able to see the keyway in the flywheel and the crankshaft. These two keyways should be aligned. If they are not aligned, the key is sheared and needs to be replaced.

I have found a video that shows how to access the flywheel key. Click here to watch the video.

I hope this is helpful. Please let me know if you need further assistance.

If you do not feel confident repairing this problem yourself, then you can have it repaired by a Sears technician. Here is a link that will provide the nearest drop-off locations: Sears Home Services .

Thank you for using Manage my life.
