Craftsman Lawn Mowerf won't Start

I have a craftsman lawn mower 7.0hp. it was working fine last week, but yesterday I took it out and started up relunctantly but worked for 2 minutes and quit. And I could not start it any more. I thought it was flooded, so I waited till this morning and tried again, still could not start. I got the resistant, but no starting engine sound. Could anyone tell me what maybe causing it. I did not notice anything wrong except yesterday was 111 degree with heat index.
appreciate your help.

One thing to check for is the oil level, is it way above the mark and smells like gas?

Not knowing the model, type and code nums for engine, i was speculating the float needle in carb was not shutting off fuel flow, and gas draining into crankcase.

Post the engine mfg and model numbers so we know what you have.
Some things to check, remove the spark plug and see if it is wet, see if you have spark, put a little gas directly in the plug hole and see if it will fire, as previously stated check the oil level to see that it is not over full, check air filter to see if it might be saturated, try some of this and report back your findings. Have a good one. Geo

Thanks Geo. I tried to remove the filter and try start the engine and it worked. That means the filter is bad. So I have replace the filter now, right?

Is the filter very dirty, wet, oily, etc. Did you tilt the mower with the carb down, if so it will let fuel/oil pass through the carb and saturate the filter rendering it useless, never tilt a mower with the carb down, that is a no,no. Anyway sounds like you are on the right track, if it runs without the filter and doesn't run with the filter, sounds like it's the filter, however don't just replace the filter without checking why it was the problem because the problem will just repeat. Have a good one. Geo
