Craftsman lawn mower doesn't start (or stalls after 2 seconds)

Hi all,
Craftsman lawn mower with Briggs Stratton Engine model 110P 02 0003 F4, 175cc OHV, 7.25lbs-ft torque, 3 years old. Engine will not start at all or starts but stalls in a second or two. And can't restart it after that. I removed the spark plug and it was wet with fuel. I cleaned it and dried it. I reinstalled the spark plug but I didn't connect the ignition boot/terminal  to the spark plug. Instead I had my friend holding the boot/terminal approx 1/2 inch away from the spark plug itself. Pulled the cord and the engine started fine and kept running as long as the ignition boot/terminal was maintained at approx 1/2 inch away from the spark plug. So I then connected the boot/terminal to the spark plug as it should be. Pulled the cord a few times but wouldn't start (or barely sputters and dies in 2 seconds and won't start again). I'm stomped....... Can anyone help?

Thanks.
Mike

    I think the first thing I would do is replace the plug with a new one.
     
    As it starts and runs with the wire held away from end of plug that would indicate to me the plug is shorting out but the surge of spark over comes the leaking off of spark. Might not be the best wording but try the new plug and see how that works.
