Small Engines (Lawn Mowers, etc.): Gas pouring out air filter?, starter rope, engine 143

Question
Hello,
I inherited (now I know why) a Crafrtsman 6.0 lawnmower with a Tecumsah engine (143.986004) Carb is (640026 or TEC-64026A).  Fuel line was missing and breather line leading away from nylon elbow consisted of a 4 inch piece of fuel line plugged into nothing?  First I emoved float bowl and cleaned bowl and holding bolt. Then I ran a length of fuel line from tank outlet to the metal intet just above primer bulb on carb body. I put some gas in the tank and pulled the starter rope a couple times and gas came pouring out the air cleaner? Can you please help me troubleshoot this issue.
Thanks,

Answer
HI KEN

SOUNDS LIKE THE FLOAT AND VALVE MY BE STUCK OR STICKING OR POSSIBLY DEBRIS HOLDING IT OPEN

FLOAT COULD HAVE HOLE IN AS WELL  ?

TRY RESETIING FLOAT LEVEL IF ITS ADJUSTABLE

ARE YOU SURE YOU STUCK THE FUEL LINE ONTO THE FUEL INLET  FOR THE CARB ?


HAVE A LOOK AND LET ME KNOW WHAT YOU FIND
