Model #917377271 Craftsman walk behind lawnmower, gas

Question and Answers

Q:

I have a Craftsman mower, model 917377271. The drive wheels won't turn. Its not the belt or cable.

A:

You can see a parts list and diagram for the lawn mower at [www.searspartsdirect.com]. Inside the gearcase item 11 moves item 15 into the gear (item 14) to cause it to drive. Item 15 is attached to the axle shaft by the woodruff key (item 18). When the drive lever is relaxed everything should turn freely. When the drive lever is moved to the drive position, item 15 causes the gear to drive.

I think you will find your problem here.

Q:

Is there a way to adjust the drive control speed on a Craftsman 917377271? It pulls fine, not fast enough.

A:

There is no adjustment to make the mower drive faster or slower. It is possible your drive belt is worn or stretched. Remove the belt cover from the front of the mower deck. Visually inspect the belt for wear. With the engine not running engage the drive control lever and see if the belt gets tight. If the belt is worn or the belt does not get tight, replace the belt.

Q:

My mower starts but I must push the primer every 5 sec or it will be starved of fuel. After 5 minutes it runs without the pumping but it still sputters.

A:

The problem is caused by the carburetor running too lean. Check the air cleaner and clean or replace it. If the fuel you are using is more than 5 weeks old, get fresh fuel.

If these things don't help, replace the carburetor.
