O.S. Engine OS29081719 Carburettor Retainer  [OS29081719]

Carburettor retainer for RC engines

This retainer serves as a compact mounting and securing component for a carburettor assembly on RC-scale engines, helping keep linkage alignment consistent during running and setup. It is presented as a replacement or service part compatible with O.S. engine carburettors and intended for model engine use only.

Installation is straightforward: the retainer locates around the carburettor body or linkage area to reduce lateral play and maintain throttle geometry. When fitting, verify alignment of the throttle arm and linkage with the retainer in place, avoid over-tightening fasteners which can distort linkage motion, and confirm full throttle and idle travel before field testing.

In tuning contexts the retainer contributes to repeatable throttle response and stable idle by limiting unwanted movement at the linkage pivot. Use it as part of carburettor setup routines when adjusting needle settings or throttle stop positions to ensure adjustments remain consistent between runs.
