Mixture screw leaking

[Kentish]

as I said you may need to strip the carbs, still dosnt explain why petrol would come out of a mixture screw it should come out over the bottom of the float bowl, glad its sorted 

Yeah I know, Well I have found in the past if some dirt gets wedged in the float valve it can cause it to stick open. Sometimes doing what I did can clear it...Flushing new petrol though it....But then an o-ring thats not been seated on the screw properly could cause it..Oh I dunno....
