:( I mistakenly put a gas oil mix into my 4 cycle lawnmower and before I realized what I did I flooded it with the gas oil mix and now the mower won't start.

Drain it and put in the right gas and if it's flooded, I've seen it take as long as 24 hours to sit untouched and then not be flooded and to start right up again (be sure the spark plug is on)
