Float chamber (without drain) -DELLORTO- PHBN, PHVA, PHVB - carburator Ø=10-12-14-17,5-18mm

Please note: Piaggio 50-80cc automatic cars (not PK automatic) generally use PHVA carburettors. The Hyper2 engines (from approx. 2001 onwards) use their own float chamber.

This has a drain with hose as well as a drain screw.
These carburettors require the float chamber with article number 1484704.

If it drips out of the hose, it is not the screw that is leaking, but the carburettor is overflowing because the float needle is leaking or the float needle seat is blocked.
The screw is only used to drain the fuel, e.g. for dismantling the carburettor or cleaning purposes.
