cool well done ,the fuel may well have thinned the oil out your right best to change it anyway to be safe usually the oil level will rise though if its had fuel getting past the piston and into the crankcase,take care ,adam

the fuel tap must be faulty and the float needles or seats cannot be sealing properly as really you should be able to leave the fuel on without a problem also it could be a badly adjusted float height or damaged float filling with fuel and therefore losing its bouyancy to shut the fuel flow off ,ok adam
