Question and Answers

Q:

Model 917.271021. Mower starts fine, runs until well warmed up and then dies. Won't start for a while. 917271021 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 shutting off intermittently. I know how frustrating that is.

There are two common occurrences for this type of issue to happen. It could be a non-venting fuel cap, or it could be an issue with spark.

Next time the tractor bogs down or dies, unthread the fuel cap and see if it smoothes out or starts back up. If so, a fuel cap replacement will be needed. The fuel caps need to vent, otherwise negative pressure builds in the tank and restricts fuel flow. After time, the pressure releases and it can be restarted. 

The other factor would be with spark. Next time it dies, take out the spark plug, reattach it to the boot, and ground it to the metal cylinder. Have someone sit on the seat and turn the key on while you check for spark. If you do not have spark, the spark module may need to be serviced or replaced. 

Another factor would be debris in the carburetor, as the symptom is not as common, it can occur. Debris gets sucked into the jet which kills the engine, and once it dies the debris falls out of the jet which allows the engine to be restarted. 

I hope these suggestions help, and thanks for using SearsPartsDirect.com. We appreciate your business.

Q:

belt to tight 917271021 Craftsman Tractor

A:

Thanks for the inquiry and for being a valued member. 

I recommend checking the routing of the belt. If the belt is routed on the wrong side of the keeper, it makes the belt too tight and the blades will not turn off. Be sure to remove the mandrel covers to see if the belt is on the right side of the mandrel brakes.

If the belt is routed correctly, park it on a hard level surface and remove the key. Then look for the return spring on the idler arm. The spring connects between the idler and the front of the deck. This spring is there to pull the idler back to loosen the belt and apply the brakes. Each brake arm has a spring also that pulls the brake into the mandrels.

If the springs are ok, check the cable. The cable should be loose when you disengage the places. If it is not loosening when disengaged the cable need to be replaced. The last check to make is on the idler arm. The idler arm has a cam that releases the brakes. I have seen the arm get worn spots where the brake lever rides and cause the mower to not disengage.

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

Q:

NOT GETTING FUEL AT CARB, OR SPARK WITHOUT REMOVING IGNITION MODULE WIRE. FUEL FILTER IS FINE, IGNITION SWITH IS FINE. STARTING FLUID WOULD ALLOW IT TO START, CRAFTSMAN #917271021, KOHLER #CV15S-4...

A:

Thank you for choosing SearsPartsDirect.com. I will be more than happy to assist you. I can understand any frustration you may have experienced with regards to your unit. Let’s see what we can do for you.

There would be to main parts I would check here. First would be the fuel solenoid aka fuel pump. It sounds like this could be the main part in not getting fuel to the carb. Also check the fuel filter, and make sure it’s flowing in the right direction. 

Another thing I would check out would be if that carb is clogged in any way. There are normally two ports that deliver fuel to the carb. One is for starting, and one is for running. If you have to clean I would suggest taking a small piece of wire and going thru the carb and cleaning all the wholes out. 

 

Hope this information has helped you. If you are not comfortable doing this repair you can click here to schedule a technician or call toll free 1-800-469-4663. Again, thank you for choosing SearsPartsDirect.com.
