Saturday I tried to start our push mower that hasn't been used in 2 1/2 years.  I couldn't keep it running.  I normally run the engine out of gas at the end of the cutting season.  However, when I looked in the gas tank Saturday there was a little gas in the gas tank when I looked at it Saturday.  I might not have run the engine out of gas 2 1/2 years ago although that would surprise me.
Thus, I drained the gas tank.  Then I put fresh gas in the tank, took off the air filter, and sprayed carb cleaner in the carburator and tried to start the mower.  The engine would run roughly, speed up, slow down, speed up, slow down, etc. and die within about 30 seconds give or take.  I tried this proceedure several times without any improvement.  I guess my on-site small engine mechanic will have to take a look at it.
I then raked some grass clippings off the front yard to keep from killing the grass.  My little girl played in the yard and in the woods beside the yard while I raked.  I really enjoy having her around when I'm working outside.  It's need to see how much she likes being outside.  
Next I mowed with the riding mower the 2 foot high grass at the entrance to the property at the street.
