I am repairing a craftsman snowblower and there is fire and I cleaned the carb and it still won't start. I checked the fuel flow and it is good but it is blowing fuel out the carb when i turn it over. I tried pouring fuel in the spark plug hole and it will kick but won't start. The carb has a primer and choke on it. When the guy brought it to me it was blowing fuel out the side of the carb when I would prime it. What would be the problem?

 

Hello racer!

If visible fuel is actually blowing back out of the carb, then you have a problem with the needle valve, seat, and/or float. I would reccomend replacing all 3. Let us know how it goes!
