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.
