Carburettor DELLORTO PHBG 20 BS 1 flexible, without separate greasing, lever choke

The Dellorto PHBG carburetor is one of the most used in the world in small displacement racing, however, size 20 remains relatively rare, this size remains an interesting compromise when the 19 seems small and the 21 seems very greedy or too big in relation to the engine configuration ...

This BS version is a flexible mounting model without separate greasing (you can always fit the grease socket to the pipe). Its starter is a lever model and its bushel / jet / needle well configuration is based on road sport, this carburetor could very well be used for racing as well as for the road. The air inlet for fixing the air filter is unthreaded in Ø33mm.
