Dellorto DHLA H Idle Mixture Screw 9656
The Dellorto DHLA H idle mixture screw meters the idle-circuit mixture at closed throttle and during the initial progression phase as the throttle begins to open. Correct screw condition and adjustment are important for stable idle quality, clean pickup, and consistent transient response before the main circuit becomes the dominant fuel system.
A worn, damaged, bent, or incorrectly matched screw can prevent accurate idle mixture adjustment and may contribute to uneven idle, hesitation during light throttle application, or difficulty balancing the carburetor. MPN 9656 identifies this idle mixture screw for Dellorto DHLA H carburetors. Use the existing screw as a reference during service and make adjustments only after confirming the carburetor is correctly synchronized and free from other idle-circuit faults.
This replacement part is suitable for carburetor service and restoration work where the original component is worn, damaged, or missing.
Reference/MPN: 9656.
Technical role: Dellorto DHLA H idle mixture screw, MPN 9656, meters the idle-circuit mixture at closed throttle and initial progression.

Important Fitment Note
Verify the carburetor family and the marking before ordering: this part is identified for Dellorto DHLA H applications and carries MPN 9656. Compare the replacement with the removed screw for overall length, threaded section, tip geometry, spring or retaining arrangement if applicable, and the seating interface inside the carburetor body. Confirm that the thread and tapered seat match; an incorrect tip or seat can damage the adjustment passage or prevent reliable idle-circuit calibration.
Compare the original part and its code before purchase.
