Removed carb last night and cleaned it good/blew some air through the jets. Now, with carb installed and pressing the primer ball, I'm actually seeing gas come out of the bottom port or jet (where butterfly is) and at a bottom port where there is a small brass screw (screw has hole through it). It's much more obvious as engine running. I can't imagine this being normal being the gas eventually runs down the side of motor.

Did I mess something up last night when cleaning carb? Reason I cleaned it was because I kept having major bog down issues anything at 1/3 throttle. Help. Thanks.

Re: 80 hp mercury carb problem.

Did you reassemble the carbs with new gaskets, needle and seats? Check the float level?
