Hi Gazza
A couple pictures would help a bit, I am not really familiar with these little ones. I had a look at the parts list though and I would suspect a hose has been hooked up wrong. I would say the reason it floods when you connect the hose is the you are blocking the atmosphere vent from the carburetor bowl. that hose should go down to the bottom of the case with the drain hose. On the parts list there is a Tube valve breather that goes from the fuel valve down and out the case as well. Would need a pic of the valve to confirm what the hose should do.
