Rear Wheel drive issues 917377110 Craftsman Gas, walk behind lawnmower

A:

Thanks for the inquiry and for being a valued member.

I am sorry to hear of the issue you've had with the rear wheels on the mower. I know how frustrating that is.

The mower locking up when pulling backwards is typically an issue with the drive pawl (175098) within the pinion assembly. Normally a good cleaning of the assembly will do the trick, but if not, you may need to replace the LH and RH pinion assemblies. I would start by disassembling and cleaning them, and inspect for any wear. 

I hope this helps and thanks for using SearsPartsDirect.com. We appreciate your business.

Ok, I have done this. Took the LH and RH pinion assemblies off and cleaned them, and looked at the pawls, which on one looked a little out of place. Other than this they looked fine. Did not really see any wear, especially on the gear teeth. Do you think it could be a problem with the gears inside the gear case assembly, part #183699? Don't really want to replace that part, it is over $70.

Q:

Engine will not keep running 917377110 Craftsman Gas, walk behind lawnmower

A:

Thanks for the inquiry and for being a valued member.

I am sorry to hear of the issue you’re having with the mower stalling. I know how frustrating that is.

It sounds like the primer is working since it is priming the engine enough to start and stay running if primed. This will be a carburetor issue. It’s probably dirty and needs to be cleaned. You probably have a clogged jet or a sticking needle.

I would pull the carb from the engine. With a full can of carb cleaner, a wire brush, and a bread tie wire to poke through and clean the main jet; I would recommend a very thorough cleaning. Start by taking off the float bowl. Douse it very liberally with carb cleaner, and undo the pin for the float, and remove the needle and float. Clean them very thoroughly with the wire brush and carb cleaner. Pay close attention to the seat the needle sits in and clean it well. Once clean, start brushing the carb bowl and body and make sure you get all the varnish out. It may take three or four brushings with carb cleaner dousing in-between. From there, take the straw of the carb cleaner and shoot carb cleaner through any little hole or passageway of the carb. Shoot out the throat of the carb and poke the main jet with the bread tie wire. You have to make sure you get everything the first time, if you leave anything behind, it’s likely to reclog once you have it reassembled.
