If there are no other screws holding the bowl then the anti-afterfire solenoid doubles as the bowl nut. Disconnect the electrical cable from the solenoid and then unscrew the solenoid using the appropriate open end wrench. DO NOT twist the larger diameter body of the solenoid (coil) with pliers or any other tool. Take care you don't lose the small round bowl gasket on the end of the solenoid.

This is a common problem. The needle and seat are prone to being held open from debris, old fuel (these days it only takes a month for fuel to start to go bad) and poor mower design. The weight of the fuel from the tank can be enough to overpower the float system with just the slightest "gumming" of the needle seat. Also, if it's equipped with an electrically powered valve on the bottom of the float bowl, this unit can outright fail, get gummed up a bit, or the electrical system have a problem and power is getting to this unit while switched off, leaving it open thus passing fuel. Most likely, replacing the needle and seat, giving the carb a good cleaning will solve your problem, however if there is damage to the seat from age or debris, just install a 2 dollar in line shut off valve available at most retailers. Then just turn the fuel on and off manually. Cheap fix. 2. Drain the oil from the engine, refill with new oil and just a oz. of atf (automatic trans fluid). Crank the engine with plug wire disconnected for 30 sec or so, then connect the plug wire. Start the engine, but only let it run near idle for a minute or so. Drain again, letting the crankcase "air out" with all plugs\dipstick removed. Remaining fuel will evaporate. Refill and your off and cutting......The ATF is a detergent of a type and will help to collect the fuel from the surfaces inside the engine. It's important to note the fuel will have washed any lubrication properties from the oil, and damage to the journals and other surfaces can happen if the engine is run too long. Usually following the above procedure will limit damage and the engine should be good for many more seasons. Good luck! Papa

check valve clearance. if ok you going have change carb.sometimes i rebuild a carb everthing seam ok but carb wont work right so i have get a new carb and it works fine evertime
SOURCE: need setting for carb. adjuster on bottom of carb
Turn the adjusting screw all the way in until it LIGHTLY seats. Now back it out one and one half turns. Do the same adjustment for the throttle screw on the right side of the carb. You are now back to the stock factory settings.
Could you take a moment and rate my answer? Thanks!
