QUESTION: hi paul ,many thx  its a vauxhall astra club 1599cc,

Answer
are you sure it has a carb? what year is it? if it is a carb then it is more than likely a stuck float valve causing the flooding, but with an EGR it is highly unlikely to have a carb and more likely to be a single point injection which does not have a float valve. I would look over the ignition system (change pugs and leads, coil/distributor) the smell of fuel would be explained by unburnt fuel going through the engine (mis-firing) check it out and get back to me
