View Full Version : Petrol dripping from carburettor breather hoses

After starting my 2000 curvy yesterday I very quickly had a small puddle of petrol underneath it. :smt086 I traced it to the pair of breather hoses that peek out from underneath the carbs. What causes petrol to run out of these? I did some searching on the forum which suggested it might be something to do with the carb floats. What should I check? The Haynes manual shows a complete overhaul but hopefully that's not necessary... :-k

If it is the floats try tapping the carb float bowls with a spanner or something solid.The problem is often caused by a bit of flotsam jamming the valve and this can dislodge it.

Yup float bowls but I'd strip them down properly

Thanks guys. :thumbsup: I'll try tapping the float bowls and if that doesn't work I guess I'll have to take them apart.

One way that does sometimes work is to drain the carbs using the drain screws, assuming the problem is just a bit of crud in the float value this can sometimes dislodge it.

The other side of this coin is that sometimes the drain screws never re-seal and you have to strip the carbs anyway.... ;-)
