Idle Mixture Screw for Weber DCOE / IDF / DCNF / DMSA Carburetors – Brass, Later Type

MPN 64750.003B – later-type mixture screw
The screw’s tapered metering end interfaces with the carburetor’s mixture passage, so the tip profile and overall interface must match the carburetor body. A bent, damaged, worn, or incorrect screw can prevent consistent adjustment, cause poor idle response, or make progression tuning difficult. This replacement is the later type; early Weber carburetors use a different screw with a larger, shorter end.

This replacement part is suitable for carburetor service and restoration work where the original component is worn, damaged, or missing.

Reference/MPN: 64750.003b.

Technical role: Brass idle mixture screw, MPN 64750.003B, for metering the mixture passage on compatible later-type Weber DCOE, IDF, DCNF, and DMSA carburetors.
Service relevance: A worn, bent, or incorrect tapered screw can impair idle adjustment, idle response, and progression tuning.

What Is Included

One brass idle mixture screw, MPN 64750.003B
Made in EU.

Important Fitment Note

This part is intended for the later-type configuration used with compatible Weber DCOE, IDF, DCNF, and DMSA carburetors. Early Weber applications may require a different mixture screw with a larger and shorter end.

Verify the screw style before ordering.
Confirm the carburetor family, body identification or code marking, and the mixture-screw interface. Compare the replacement’s threaded section, tapered end geometry, seating profile, and overall length with the removed screw and the carburetor’s original adjustment hardware. Do not rely on carburetor family alone when early and later screw designs are both possible.
