This MBD made 3.5mm fast flow float needle valve is used on PHBH, PHBL and VHSB, VHSA and VHSH type Dellorto carburettors to help solve the fuel starvation problem they suffer when used on Lambrettas and Vespas when fitted with a standard 2mm (or 200) smaller valve.
Made from Viton to help with modern fuels.
These work on any engine of any size standard or tuned which are using smaller valves.
