Weber 48 DCOE / DCO / IDF Throttle Plate Butterfly Valve 78° - MPN 64005.108
This genuine Weber throttle plate is used in 48-series IDF, DCO, and DCOE carburetors to regulate airflow through the throttle bore. Its opening angle and edge geometry influence the relationship between throttle-shaft movement, airflow progression, and transient response. A worn, bent, incorrectly angled, or damaged plate can prevent the throttle from closing correctly, affect idle control, or create inconsistent progression as the throttle begins to open.
78° throttle plate specification Verify that this angle matches the original plate and the carburetor’s throttle-shaft arrangement before installation. The plate is identified by Weber MPN 64005.108 and is suitable for service or rebuilding work where the original throttle butterfly requires replacement.
This replacement part is suitable for carburetor service and restoration work where the original component is worn, damaged, or missing.
Reference/MPN: 64005.108.
Technical role: 78° throttle butterfly plate for regulating airflow in Weber 48 DCOE, DCO, and IDF carburetors.

Important Fitment Note
Verify the carburetor family before ordering: Weber 48 IDF, DCO, or DCOE. Confirm the marking or part number against MPN 64005.108, then compare the removed plate for diameter, 78° opening specification, edge profile, mounting-hole position, and throttle-shaft interface. Check the screw-hole pattern and the plate’s orientation relative to the shaft and bore; a plate with different geometry may not close, seal, or align correctly. Thread and seat/interface details should also be compared with the original assembly where applicable.
Compare the new plate directly with the removed part before installation, especially if the carburetor has been modified or rebuilt.
