O.S. Engine OS29081719 Carburettor Retainer for O.S. engine carburettors  [OS29081719]

Stable carburettor mounting for RC model engines

This compact retainer provides a secure locating point for a carburettor assembly on RC engines, improving linkage stability during use and adjustments. It is offered as a replacement/service component compatible with O.S. engine carburettors and suitable for hobby engine applications only.

Installation is straightforward: seat the retainer around the carburettor body or linkage to limit sideways movement and preserve throttle geometry. During fitting, confirm the throttle arm and linkage alignment, avoid over-clamping which can distort motion, and check full throttle and idle range before track or field use.

As part of tuning routines the retainer supports repeatable throttle reaction and steadier idle by restricting unwanted pivot movement. Fit it when adjusting needles or throttle stops to keep settings stable across runs.
