O.S. Engine OS29081719 Carburettor Retainer Upgrade for Linkage Stability  [OS29081719]

Linkage stabiliser for carburettors on model engines

This retainer provides a neat mounting point to secure a carburettor assembly on RC engines, reducing linkage play and keeping throttle geometry steady. It is supplied as a replacement or service item compatible with O.S. engine carburettors and intended solely for model engine use.

Installation is direct: the retainer locates around the carburettor body or throttle linkage to limit lateral movement and maintain correct geometry. When fitting, ensure the throttle arm lines up with the retainer, avoid over-tightening screws which can impede motion, and confirm full throttle and idle travel prior to operating the model.

In tuning scenarios the retainer promotes repeatable throttle response and more reliable idle by preventing slack at the linkage pivot. Include it in routine carburettor setup when adjusting needles or throttle stops to lock in consistent results.
