O.S. Engine OS29081719 Carburettor Retainer — Linkage Security Part  [OS29081719]

Carburettor linkage retainer for hobby engines

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

Fitting is straightforward: place the retainer around the carburettor body or linkage area to reduce side-to-side play and preserve throttle geometry. During fitting, check throttle arm alignment with the retainer in place, avoid overtightening fixings which could bind the linkage, and confirm full throttle and idle movement before any field test.

When tuning, the retainer supports repeatable throttle reaction and steadier idle by restricting unwanted movement at the linkage pivot. Integrate it into carburettor setup work when adjusting needles or throttle stop positions to keep settings consistent between runs.
