Starting at $22.95, AutoBuffy stocks 1 carburetor accelerator cable bushings from URO. This small plastic or nylon bushing anchors the throttle cable to the carburetor linkage arm, translating pedal movement into precise throttle response. When it cracks, swells, or falls out, the cable loses its fixed pivot point, causing sluggish acceleration, a sticky throttle, or complete loss of throttle control.
The most important factors are material and dimensional fit — bushings come in nylon, plastic, and sometimes brass, and the inner bore and flange diameter must match your carburetor's linkage pin exactly. A bushing that is even slightly undersized will wear rapidly, while an oversized one introduces the same slop you are trying to eliminate.
| Option | Best for | What you get |
|---|---|---|
| OEM-spec nylon bushing | Daily drivers and stock restorations | Exact factory dimensions, correct friction coefficient, quiet operation with no modification needed |
| High-durability polyurethane bushing | High-heat engine bays or performance builds | Greater heat and chemical resistance than standard nylon, longer service life in demanding conditions |
| Brass or metal bushing | Vintage or heavy-duty applications with worn linkage pins | Maximum wear resistance, suits applications where plastic has repeatedly failed, may require light fitting |
| Multi-piece repair kit (bushing + clip + grommet) | Complete linkage slop or unknown bushing history | Replaces all wear points at once, eliminates guesswork, best value when cable end hardware is also worn |
With the engine cold and the air cleaner removed for access, use a pick or needle-nose pliers to remove any retaining clip, then press or pry the old bushing out of the linkage arm. Clean the pin and hole of any debris before pressing the new bushing firmly into place and reconnecting the cable end. Before reassembling, operate the throttle by hand to confirm smooth, full-travel movement with no binding or slack.
