Small Engines (Lawn Mowers, etc.): Craftsman Kohler Command, jet nozzle, jump wires

Question
I have a Craftsman riding lawnmower (model # 917.258590) with a Kohler engine (model # CV16S type # PS-43509). The engine turns over but will not start. The spark is good and the fuel pump is pumping fuel to the carburetor. I have taken apart the carburetor and cleaned it. Still not starting. What do I need to check now?

Answer
HI CARL

TRY REMOVING AIR FILTER AND PRIMING CYLINDER THROUGH AIR INTAKE INTO CARB IF UNIT RUNS  ON WHAT YOU PRIMBED IT ON THEN  FUEL IS NOT GETTING FROM FLOAT BOWL TO MAIN JET/ NOZZLE AND INTO VENTURI  AND INTO INTAKE MANIFOLD

HAVE YOU CHECKED THE  FUEL SOLENOID IS GETTING 12 VOLTS THIS OPENS THE FLOW TO MAIN JET WHEN IT GETS 12 VOLTS  IF NOT   YOU HAVE A BAD WIRE FROM SWITCH TO CARB SOLENOID - CHECK AND REPAIR

AS A TEST ONLY TRY USING A SMALL 12 VOLT BATTERY WITH SMALL JUMP WIRES ON IT  AND COUPLE THEM IN ON THE SOLENOID CONNECTOR @ CARBY  AND SEE IF STARTS UP   IF IT DOES   ABOVE IS CONFIRMED

ARE VALVES OPENING AND CLOSING ?

DOES UNIT HAVE GOOD COMPRESSION  ?


GIVE IT A TRY

LET ME KNOW WHAT YOU FIND
