You should let the old fuel out and get some new fuel. If it has a set of points for the spark timing make sure they are clean and don't have a spike. Make sure the air filter is clean. You may have flooded it or maybe the other way, not enough fuel. You can clear the flooding by taking the spark plug out and cranking it to blow out the cylinder.
