Craftsman mulcher mower; has started hard in the past. after the 3 hits to prime it would start then die. If you hit the prime button quickly you can keep it running and it gets better. Today when I went to start it, it refused to start. then I noticed gas leaking out the air filter . any ideas?

Carb. float must be stuck open. First if you have no fuel in the tank it must all be in the crankcase.Drain the oil and refill and also check the carb as the float has to be sticking open. Hope this will help you. Donnyb60

SOURCE: mower starts w/ priming but stops after 1-2 seconds. Air filter, gas, oil, spark plug are new
Remove your fuel filter (in the tank usually) and, replace it
SOURCE: toro recycler will run until primed gas is consumed.
The problem is that the gas that sat in the carb all winter glazed it over and gummed it up. Begin by going to any auto parts store, like an aiutozone, and getting a bottle of carb. cleaner. Seafoam is one I use. Add it to your gas, one ounce per gallon of gas. Also, pick up a can of engine starting spray.
Remove the air filter and spray the engine starting spray into the air intake. Pull start the engine and give it additional squirts of engine starting spray until it runs smoothly.
SOURCE: toro personal pace mower 5 yrs old only runs 10-15 seconds.
Was gasoline left in the tank during off season? Sometimes gas will break down and clog the jets in the carb. The priming bypasses the carb so when you put fuel in by pumping the bulb it runs, but dies becasue no additional fuel is coming through the carb after the primed fuel is burned off. Sounds like you need to clean the jets in the carb and in the future, use Stabil in gasoline to keep it from breaking down.

I've got the same problem with the gas leaking out of the air filter when I push the button. What the hell is that all about?
