So I got a craftsman pressure washer with a Briggs and Stratton 6.75 hp motor. The motor does not run. I changed the air filter oil and spark plug. Still not working. I then overhauled the carbureator cleaned the fuel lines. Still not running. I am besides my self on this one. I looked in the intake and exhaust ports top of the piston and all looks good. Not showing signs of oil leaking beyond the piston rings. If there is anything anyone can think of that I haven't thought of please give me some insight as too what the possible cause might be. I am not trying to put anymore money into this thing than I already have.
