My craftman snow blower starts then stop

This is kind of vague. Did you try pushing a fuel priming bulb if it has one. If you push that bulb and it continues to run, then you have a fuel blockage. There are several places a blockage can occur, fuel filter (if present) or carberetor. Possible a fuel scren on gas tank. Did you check the condition of your fuel? If it is last years gas, dump it out and replace with new. Today's gasoline blends begin to degrade in a month or so. A year and many small engines will not operate.
