    I have a problem with my 6hp Briggs n Stratton lawn mower. I push the purge and the engine will run for about 5 seconds then start to cut out. If I keep pushing the purge button, it will keep running...Any thoughts about this?...Ziggy

    Do you mean the fuel primer button? If thats what you mean the carburetor is cloged. Try and clean out the jets with a carb. cleaner spray.

    When is the last time you cleaned the tank and changed gas? Try that and spray a little starting fluid in the carb. if you have any.

    Try cleaning your air filter and carburetor, its a fuel problem for sure. Gas engines have only two things to check. It's either fuel or spark. Yours is fuel. BRGII

    If your primer ball has a hole in it it will suck air. I have had outboards do it and it is a pain. They dont't cost much so if that is not it you won't be out but a buck or so. Good luck JIM

    You need to get rid of any stale (old) gas replace with new and get a new plug and filter for starters. If that doesn't cure the problem then take the model and serial number and get a carurator rebuild kit if your mechnically inclined and rebuild the carb that wil do it.

    STRAIGHT 99 IS ON THE MONEY. MINE DID SAME THING. TOOK OFF THE BOWL AND CLEANED OUT JETS AND OTHER ORIFICES WITH JETSPRAY. THERE WAS ONE SMALL ORIFICE ON THE SIDE OF THE TUBE I HAD TO CLEAN OUT WITH A SAFETY PIN THEN SPRAY. IF
    IT RUNS GOOD AFTER THAT THEN CLOGS AGAIN YOU ARE LOOKIN AT CLEANING OUT YOUR GAS TANK AND/OR OR ADDING A SMALL INLINE FILTER IF THERE IS A HOSE FROM TANK TO CARB.

    Try a tank of premnium fuel - which typically has better detergents in it or a fuel injector cleaner.

    Make sure you clean the needle and seat too.

    Mine did exactly the same thing, and cleaning the needle and seat took care of the problem.

    What? Man, just go buy a new mower then. There are some things you just don't inquire about here. To many lights half lit.

    It is likely the floats needle valve that is stuck shut, I bet when you remove the bottom of the carb bowl, it is empty of gas.....

    Rap the carb with the plastic handle of a good size scredriver, if you have a sticky float it might free up.

    Lots of good suggestions here.

    I have a different take. I'd be willing to bet that the fload bowl is filled with water. Hitting the prime button bypasses the fload system and shoots pure gas into the venturi. The machine runs until that gas is used up. The fix is simple.

    1. drain the old tank and blow out the gas line. Nothing drastic, just blow in it with your mouth..Reinstall the gas line.

    2. take the bowl off of the carb and empty it. See if there was water in it. If so, you are mostly done.

    3. reistall the bowl.

    4. add fresh gas mixed with Stabil

    5. pull the starter a few times, push the prime bulb 7 or 8 times and pull the handle. It should start right up.


    I go through this every couple of years with my chipper and or my generator. Condensation builds up and water gets through. Remember, the gas floats on the water so your pick up will suck water before it sucks gas.
