Small Engines (Lawn Mowers, etc.): Bad gas, gas oil, lawnmower

Question
My wife accidently put my gas/oil mix fuel for my 2 stroke trimmer in my lawnmower - ran it across the yard and it stopped running - how do i fix this?

Answer
It is unlikely the mixed fuel caused whatever your problem is.  I occasionally use mixed gas because it's all I have on hand (and I'm too lazy to run to the gas station!).  Unless it was mixed so improperly it has fouled the spark plug, you will need to investigate other problems.  Please write back with other symptoms or what you find (fouled plug, won't restart when warm, runs only on choke, etc.)
