Daves,do not increase the RPM based on sound,the Briggs Vanguards are very smooth and quiet. I thought mine was set to slow also,but i checked it with a handheld RPM tachometer,the RPMS were perfect,the engine just sounds like its loafing along,where as my Kohler at the same speed sounds like its coming unglued.

Make sure the throttle is moving all the way open. If the RPM's are correct (and they probably are) any attempt to gain RPM's via the governor will cause a lean situation with no high speed screw.....Mike
