Pump Rod Plunger Spring Weber 46/48 IDA 35/38 DCNL – MPN 47600.103
This pump rod plunger spring is used in the accelerator-pump mechanism of Weber 46/48 IDA and 35/38 DCNL carburetors. It returns the pump rod and plunger after actuation, helping restore the pump assembly to its ready position for the next throttle movement. A damaged, stretched, missing, or incorrectly matched spring may contribute to delayed plunger return or inconsistent accelerator-pump response during throttle transitions.
MPN 47600.103 Verify the spring against the original pump assembly before installation. The correct spring must work with the existing pump rod, plunger, guide, and retaining arrangement; it is not a substitute for inspection of the plunger bore, rod alignment, or accelerator-pump circuit condition.
This replacement part is suitable for carburetor service and restoration work where the original component is worn, damaged, or missing.
Reference/MPN: 47600.103.
Technical role: Spring for the accelerator-pump rod and plunger mechanism in Weber 46/48 IDA and 35/38 DCNL carburetors.
Service relevance: Supports pump-rod and plunger return after actuation for consistent accelerator-pump response.

Important Fitment Note
Verify the carburetor family and application before purchase: Weber 46/48 IDA or 35/38 DCNL. Confirm the part number or marking as MPN 47600.103 where applicable, then compare the replacement spring’s overall geometry, coil arrangement, end shape, and interface with the removed spring. Also check that it fits correctly around or against the pump rod, plunger, guide, and retaining features without binding.
Compare the removed spring directly before installation; similar-looking carburetor springs can differ in geometry and operating position.
