    12 hp Briggs and stratton won't start
    I have a craftsman lawn tractor that was given to me when I got it it wouldn't run so I ran some tests and found that the carb was very green and dirty so I replaced the float bowl, needle , gaskets , nozzle etc. Also replaced filters and fuel line after words it fired right up ran great I parked it in the garage and the next mourning it wouldn't start.. I went out and bought a brand new battery today installed it and it fired right up again! Left it maybe 2 hours and now it don't start I mean nothing seems like the battery's dead. Any ideas tips please help

    Try the safety switch under the seat,or
    A bad/loose terminal,or
    You left the lights /key on somehow and the battery really is dead

    Fully charge battery.. water level OK?
    Then start it up
    Then shut off
    Then unhook battery
    Then come back in an hour hook up battery
    ,see if still starts,and I'm thinking it won't

    Just because the battery is new ,it doesn't mean it is any good


    Also,maybe a defective solenoid ?
    Are you sure the battery is dead afrer an hour?
    Try tapping on the start solenoid with a screwdriver

    Sounds like an electrical short, grounding out the battery, causing it to drain it's charge.

    An electrical short? That makes sense so I should go threw all my wiring and connections and also check the starter brushes?
