Small Engines (Lawn Mowers, etc.): Stalling, briggs straton, air leak


Question
QUESTION: I have replaced the spark plug, removed and cleaned carb. My mower will start for a very short period and then stall immediately. One thing that I just recently noticed is that after pushing the primer bulb repeatedly, the fuel is dripping out of where the carb mounts to the intake. Im guessing thats flooded.

Now I cant get it started at all. Wondering if it could be the float, but not sure how a float can break or wear out.

Thanks for the model information.

There is a float needle that goes into a seat on the carburetor. Most likely you have dirt in there,causing the problems. I have a attached a pic  of the carburetor.Make sure that the fuel shutoff valve (if present)  is opened, and that the fuel line is not plugged or kinked. Also be sure the fuel cap vent is open and any screens in the tank are clear of debris. If fuel can flow to the carb, carefully place 1 teaspoon of gasoline down the spark plug hole (or a add shot of starting fluid into the carb throat). Re-tighten the plug and try to start the machine. If it runs for a second or two, then quits, chances are the carb needs to be serviced (disassembled and cleaned & inspected, then rebuilt) or you have an air leak somewhere. Make sure all mounting screws or bolts are snug and gaskets are not missing sections.
