Question

Answer
HI MIKE

1ST REMOVE FLOAT BOWL AND FLOAT AND NEEDLE

ANSWER IS NO   BUT SOAKING TIME FOR CARB CLEANERS IS  1/2 HOUR MAX NO MORE OR YOU COULD DAMAGE  THE CARB OR PLASTICS  ETC    

THEN CLEAN OUT IN PETROL AND BLOW ALL JETS AND PASSAGES - REPLACE NEEDLE AND IF UNIT HAD  WET SUMPING CONDITION OR FLOODING -  REASSEBLE  PRESSURE TEST FUEL VALVE SEALING WITH A PRESSURE TEST ( WET WITH PETROL)AND SEE IF IT HOLDS PRESSURE  AND STOPS FUEL FLOW.

CHECK FLOAT FOR HOLES  BY SHAKING  OR HOLDING UP TO THE LIGHT  YOU WILL SEE FUEL INSIDE
BE SURE TO CHECK IDLE FUEL JET AND AIR BLEED HOLES AND MAIN JET ARE CLEAN, CLEAR ALSO

CHECK THROTTLE SHAFT FOR  PLAY SHOULD BE NO FWD / AFT MOVEMENT , ( THIS WOULD INDICATE WEAR AND A POSSIBLE AIR ENTRY POINT )   ONLY ABLE TO OPEN AND CLOSE SMOOTHLY / FULLY

BE SURE TO KEEP ALL PARTS IN CORRECT RELATIONSHIP FOR REASSMBLY

CHEERS HOPE IT HELPS
