Question about John Deere Garden
AN ENGINE THAT IS "MISSING" IS NOT RUNNING ON CHOKE, WHEN IT IS CHOKED IT WILL SIMPLY RUN AT A MUCH LOWER RPM BECAUSE IT IS GETTING MORE FUEL THAN AIR. THE AIR / FUEL MIX RATIO ON YOUR ENGINE IS 14.7 TO 1; THAT IS 14.7 GALLONS OF AIR TO 1 GALLON OF FUEL. SO AS YOU CAN SEE IF YOU ARE GETTING ANY LESS AIR IT WILL RUN FLOODED.
YOU DO NOT SAY WHAT COLOR THE SMOKE IS- IF IT IS BLACK THEN YOU ARE FLOODING, AS TO MUCH FUEL WILL PRODUCE A BLACK SMOKE BECAUSE THE COMBUSTION WILL NOT BURN IT ALL, IF IT IS BLUE YOU ARE BURNING OIL. IF THE SMOKE IS BLACK, REPLACE YOUR AIR FILTER AND BE SURE IT IS INSTALLED CORRECTLY. IF YOU HAVEN'T FOOLED WITH THE CARBURETOR IT WILL NOT NEED ANY ADJUSTING.
IF THE SMOKE IS BLUE, CHECK YOUR OIL LEVEL IN THE CRANKCASE, IF IT IS OVER FULL THE VACUUM FROM THE VALVE COVER WHICH OPERATES YOUR FUEL PUMP WILL PULL OIL FROM THE CRANKCASE INTO THE VALVE COVER AREA AND WILL GET SUCKED INTO THE COMBUSTION CHAMBER AND MIX WITH THE FUEL AIR MIX AND PRODUCE POOR IGNITION COMBUSTION WHICH WILL SMOKE EXCESSIVELY AND MAKE THE ENGINE SEEM AS THOUGH IT IS FLOODED. iF THIS DOESN'T SOLVE THE PROBLEM GIVE ME AN ANSWER TO THIS NEXT QUESTION: WHEN YOU SAY IT IS MISSING, IS IT BACKFIRING, POPPING OR SPUTTERING? AND IS IT SINGLE OR TWIN CYLINDER.
