Dellorto 40 DHLA Idle Mixture Screw 8025
The Dellorto 40 DHLA idle mixture screw regulates the idle circuit’s fuel contribution at idle and during the initial progression phase as the throttle begins to open. Its tapered metering tip and threaded adjustment interface allow precise control of mixture balance between carburetor barrels during service and tuning.
MPN 8025 is identified for Dellorto 40 DHLA carburetors. A damaged, bent, worn, or incorrect screw can prevent consistent adjustment and may contribute to unstable idle, uneven cylinder response, or hesitation during low-throttle transition. Inspect the screw tip and threads whenever the idle circuit is serviced, and avoid forcing the tapered tip against its seat.
This replacement part is suitable for carburetor service and restoration work where the original component is worn, damaged, or missing.
Reference/MPN: 8025.
Technical role: Idle mixture screw for Dellorto 40 DHLA carburetors, identified by MPN 8025.
Service relevance: Restores adjustment of the idle circuit when the original screw has a damaged tip, worn threads, or inconsistent seating.

Important Fitment Note
Verify the carburetor family as Dellorto 40 DHLA and confirm the 8025 marking or MPN before ordering. Compare the replacement with the removed screw for overall geometry, tapered tip profile, thread form, adjustment-head style, and seating interface. These details control how the screw meters the idle circuit and how it seats in the carburetor body.
Compare the removed part carefully before installation; do not rely on carburetor appearance alone.
