Check base of carb for looseness or bad gasket which will cause a vacuum leak. Also, condition of fuel (water in tank, dirty filters)

Governor operation??

Sounds like there is probably some crap in the main jet of the carb -- take it off - get a gasket set and clean it out. Usually when a Briggs runs ok with the choke on but not with it off the carb is the problem -- JMHO

Stop by NAPA and get a can of carb cleaner.Dissassemble the carb completely removing all plastic and rubber parts.Pick up a carb rebuild kit from your local small engine shop.These parts are specific to your engines Model#Type# and code #s be sure you have all the #s.I use acetelene torch tip cleaners to carefully clean out all the crud that tends to build up in passages and jets in the carb.You can also use the wire in a bread sack tie.Blow out thouroughly with compressed air.Install a new in-line fuel filter,this should remedy your problems.Best of Luck:thumbsup:
