lawn mower not working

I have accidentally added petrol to the oil tank of a petrol mower I could not find and opening underneath the tank and so tipped it upside down to drain the oil tank ,and then added fresh oil it did work for a little while but now doesn't want to start or it does now and again only for about for 30 seconds and then stops with a fair degree of smoke,could anyone offer me any advice I did have a look at the spark plug and it looked to be quite oily I don't know if this is supposed to be like that,maybe tipping the mower upside down helped oil to spread to other parts of the mower unintended

The Air Filter will be located on the side, or the top of your Carburettor. On a Briggs and Stratton 220 Series this is where your "Red Primer Button" is for cold starting. See the following link for all your Briggs and Stratton Spare Parts - 'Briggs & Stratton Spare Parts - Lawnmower World'
