This spring is used on both ends of both the primary and secondary throttle shafts in the Weber DGV carburetor (total of 4 springs per carb). They keep the nylon Throttle Shaft Retaining Bushing (sold separately) in place, but they also help to keep the throttle linkage parts from binding against the carburetor body. They even help to keep the throttle shafts centered. Each carburetor takes 4 springs (one on each end of each throttle shaft). Sold individually.
Fits Weber DGV series (including 32/36 DGV 5A, 32/36 DGAV, and 32/36 DGEV and Weber 38 DGS series (including 38/38 DGAS and 38/38 DGES).
Does not fit any other brand or model including DFV series (32/36 DFAV, 32/36 DFEV, or 40 DFAV). For genuine Weber carburetors only, may not fit clones or "work-alike" copies.
