Thank you for choosing Sears Parts Direct. I will be more than happy to help with your lawn mower. Upon researching model917.288250 ; the first thing I want to mention is the starting fluid. That stuff is extremely hard on a small (air cooled) engine. If you are in need of something to use as a starting fluid, it would be best to directly inject some gasoline into the plug holes. Carburetor/choke cleaner (spray type) also will work quite well as a starting fluid. Actual starting fluid (ether) burns very hot and can damage a small engine rather quickly.


Moving on the actual problem at hand: If you are getting it to start with starting fluid, if it stays running, then I would say we have a situation of the choke not full engaging. If the engine starts with the starting fluid and runs for 10seconds to a minute then dies, then I would say we have a problem within the fueling system. That could be a carburetor problem or a fuel delivery problem.


If the machine sat for any amount of time (over 3 weeks), unused, with fuel in it I would suspect a problem within the carburetor. You will need to get some carb/choke cleaner and take the carb down for cleaning. Fuel over 4 weeks old will begin to break down. As it breaks down, deposits are left behind and those deposits will form a gelatin-like material that will gum up the carburetor. If left long enough, it will dry out and form a very hard varnish inside of the carburetor (ruining it in most cases).

I trust this information will help you, we appreciate your business thank for choosing Sears.

i stored my tractor over the winter with gas in it and now the carb is clogged. How do I go about cleaning the carb? 917288250 Craftsman Tractor


Thank you for being Sears’ valued member and for contacting with your question about your Craftsman tractor model 917288250. I am so sorry the carburetor is clogged with stale fuel. I will be happy to help you with this. I have included the link below for you to view our repair guides. There is one that addresses rebuilding a carburetor. This will show you how to disassemble it for cleaning.

Please note – the carburetor has multiple tiny openings that are very difficult to clean. You may find it more beneficial to replace the carburetor. I have included the link below to order the part.

I have also included the link to the manufacturer's carburetor cleaning information.
