My Craftsman Snow Thrower (Model No. 247.889571) isn't starting. I changed the spark plug, have primed it, put in new fuel and it has oil. What should I do?

debra,
It is normal for the sparkplug to be a little dirty after a few times of running. The reason is the piston rings need time to seat against the cylinder walls. I suspect the plug is fine. If you have spark at the sparkplug the problem is likely fuel related. If the snow blower was stored over the summer with untreated fuel it can gum up the passages and cause the engine not to start. To cure this, the carburetor needs to be cleaned or replaced. If you do not feel comfortable I recommend having the repair done at one of our drop off locations. Please call 1-800-469-4663 to find the closet one to you.

Please let me know if you need further assistance.

Thank you for your question.

I am sorry you are having a problem with the snow blower. First, make sure the fuel you are using is less than five weeks old. If it is full of old fuel, you can use a turkey baster to remove the old fuel. Next, be sure red key is pushed in all the way. Then move the choke lever to on and push the primer 3 to 5 times. Then try to start the engine. If the engine does not start, I suspect the problem is a dirty carburetor. To confirm this pour a few teaspoons of fresh fuel into the throat of the carburetor (the first image below will show how to get access to the carburetor.) then pull the starter rope. If the engine tries to start or starts, I recommend cleaning the carburetor. I have posted a few images below to aid in cleaning the carburetor. Once the carburetor is apart, clean all the passages with carb cleaner and a bread tie wire.

Please work in a well ventilated area and use caution when working with fuel.
