Small Engines (Lawn Mowers, etc.): Briggs Motor Stalls, briggs and stratton, fuel needle

Question
I have a rototiller with a 6HP OHV Briggs and Stratton motor.  I had to clean out the carb this spring and it idles fine, however when I put a load on the motor, the governor moves and stalls the motor.  Any suggestions?

Answer
HI GREG

SOUNDS LIKE THE MAIN JET OR EMULSION TUBE AND AIR BLEEDS ARE BLOCKED RECHECK CARB &  ALL JETS  USING   CRC AND BLOW COMPRESSED AIR THROUGH THEM  AND SEE IF  CRC COMES OUT THROUGH  JETS AND OPENINGS - CHECK FOR STUCK / STICKING FUEL NEEDLE VALVE

CHECK  VALVE  CLEARANCE  TRY CHECKING / SETTING TO  .004 "  INLET  AND 0.006" EXHAUST  

IS FUEL FLOW GOOD FROM TANK TO CARB?

IS FLOAT BOWL  CONTINUALLY FUEL OF FUEL ?

IS BOWL VENT CLEAR ?

IS SPARK CONSISTANT UNDER LOAD ?

IS COMPRESSION  OK ?

IS TIMMING KEY OK  NOT SHEARD OR BENT ?


GIVE IT A TRY AND LET ME KNOW WHAT YOU FIND


CHEERS HOPE IT HELPS
