I have a pressure washer that has a Briggs and Stratton engine that is leaking gas. I filled the gas tank out and found out that gas is leaking out through the air filter. I looked at the gas hose going from the tank to the carb. And it looked good. I took the air filter off and saw that gas was going into the air filter compartment. Is this something that I could fix (not experienced) or should I take to someone who knows what they are doing. I would like to try.
