If you did not try to start it then dump out the oil and wash out the tank with some mixed gas. If you did try to start it then wash out the tank and put some mixed gas in it and if it has a primer bulb on it push the primer a bunch of times and then try to start it. if this doesn't work you will need to take off the carb; clean it and try to get as much oil out of the fuel line as possible. If you try to do this you need to be careful not to loose the little inlet screen on one side and remember how the diaphragms go back on. This is extremely important!
