PUMP ROD for WEBER 46/48 IDA - Plunger Shaft
This pump rod, also identified as a plunger shaft, transfers accelerator-pump linkage movement to the pump plunger in Weber 46/48 IDA carburetors. Its movement controls the pump shot delivered during throttle opening, supporting transient enrichment and helping prevent hesitation or a lean bog when the throttle is opened quickly.
For Weber 46/48 IDA accelerator-pump linkage service. A worn, bent, incorrectly positioned, or mismatched rod can alter plunger travel and pump-shot timing. During service, inspect the rod for straightness, correct end geometry, secure linkage engagement, and full plunger movement through the operating range.

Important Fitment Note
Verify the carburetor family and the identification code or marking before purchase. Compare the rod’s overall geometry, bent or offset end shape, linkage interface, and plunger connection with the removed part. Check the related pump mechanism for matching thread, seat, retaining, or engagement style where applicable, and confirm that the rod allows the plunger to move through its complete stroke without binding.
Because 10410.021 and 10400.021 are both referenced, confirm the required part number and physical configuration against the removed rod before installation.
