You should also check the air filter ... if this *is* happening, then the float bowl can also overflow in the other direction - toward the air filter. You'll find the filter wet with fuel and possibly a fuel puddle in the bottom of the airbox.
Thanks slapper, cleaned out the air filter when oil was done no fuel in there but I do leave the tap on and have smelt a bit of fuel in the gararge recently, will turn it off and check the carby over the weekend. I smelt the oil and it did smell a little of fuel.
Thanks for the response
