DELLORTO DRLA, DHLA AIR BYPASS SCREW 8176
This tapered adjustment screw is used in the idle and low-speed circuit of compatible Dellorto DRLA and DHLA carburetors. Its needle-style tip meters the adjustable passage at the carburetor body, influencing low-throttle operation, progression, idle quality, and transient response. Depending on the specific carburetor configuration, this interface may function as an idle mixture adjustment or an air-bypass adjustment.
MPN 8176 is identified for Dellorto DHLA G applications. A damaged, worn, bent, or incorrect screw can prevent accurate circuit adjustment and may contribute to unstable idle, poor progression, or inconsistent cylinder-to-cylinder balancing. Verify the carburetor family and adjustment location before installation.
This replacement part is suitable for carburetor service and restoration work where the original component is worn, damaged, or missing.
Reference/MPN: 8176.
Technical role: Tapered Dellorto adjustment screw MPN 8176 for the idle and low-speed air-bypass or mixture-adjustment circuit in compatible DRLA and DHLA carburetors.
Service relevance: A worn, bent, damaged, or incorrect screw can affect idle quality, low-throttle progression, and adjustment consistency.

Important Fitment Note
Confirm that your carburetor is from the Dellorto DRLA or DHLA family and check the existing screw or carburetor documentation for the 8176 marking or matching reference. Compare the replacement with the removed part for tapered-tip profile, thread form and length, head or drive style, and the seating arrangement in the carburetor body. Verify that the screw installs into the same air-bypass or mixture-adjustment interface without forcing it.
Compare the removed screw directly before ordering; similar Dellorto adjustment screws can differ in tip geometry and application.
