Carburetor Dellorto PHDG 19 AU 4-stroke

Racing carburetor dellorto PHDG 19mm

New release 2024 from carb specialist Dell'Orto: the PHDG carburetor. The Dellorto PHDG was specifically designed for high-performance 2- and 4-stroke engines.

This is the PHDG AU variant, other sizes and variants can be found here: Carburetor Dellorto PHDG.

INFO: AN refers to the variants with perforated emulsion tube (2-stroke), AU with closed emulsion tube (4-stroke). However, this classification is not binding, as both variants function across engine types; all PHDG carburetors therefore have a 2-stroke oil port regardless of the type of emulsion tube.

Dellorto PHDG carburetor

The round, flow-optimized passage ensures a high air flow rate, direct throttle response and a noticeable increase in power. The special air intake profile delivers direct response as soon as the throttle is opened.

The aluminium body with aluminium float chamber is lightweight, low-wear and offers good heat dissipation; the anodized carburetor cover and float chamber screw plug round off the racing finish.

The aluminum throttle slide with special surface treatment reduces wear and ensures particularly smooth, precise operation.

The carburetor is equipped with a vacuum and oil port, with the oil connection fitted with a check valve to prevent dripping.

It has a 46 mm air filter connection as standard, which can be expanded to 60 mm using an adapter.
