Note

Important: In the supplier’s title, the carburetor is designated as Dell’Orto PHVA Ø17.5 RD, while the technical description lists it as PHVA Ø14 QD. The actual carburetor designation and diameter must therefore be verified before publication or ordering.

Before ordering, we recommend comparing OEM number 874672, the connections, the position of the adjustment screws and the electric choke design with the original carburetor.

The electric choke is included with the carburetor.

During installation, it is also necessary to check the correct connection of the fuel supply, two-stroke oil supply and any carburetor heating hoses.

After installation, we recommend checking the carburetor settings and proper engine operation, as an incorrect fuel-air mixture may cause poor performance or engine damage.
