Question and Answers

Q:

LT1000 - model 917272672 917272672 Craftsman Lawn tractor

A:

Thanks for the inquiry and for being a valued member.

I would suspect that it would be worth repairing. The engine isn't terribly old (approx 10-11 years), and it may be something easily fixable. The parts for the engine are available on Sears Parts by entering engine model 31C707-0230-E1. There is a complete engine gasket kit, which is part number 796187. However, you could purchase whichever gaskets/seals needed too.

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

Q:

engine quit running 917275371 Craftsman Tractor

A:

Thanks for the inquiry and for being a valued member.

I am sorry to hear of the issue you're having with the tractor. I know how frustrating that is.

I would suspect the carburetor initially. I would pull it from the engine a do a thorough cleaning on it. If that doesn't help get it fired, then you may have a valve out of adjustment, and you will likely need to adjust the intake and exhaust valves. The intake should be set to .003-.005" and the exhaust should be at .005-.007". I have linked the manual for this engine below.

This sounds like an issue with the valves being out of adjustment. Based upon the Briggs manual, the intake valve should be set to .003"- .005", and the exhaust valve should be set to .005"-. 007". There are some great YouTube videos you can watch to see how the valves are adjusted if you've never done it before.
