YS Engine YSF5165 FZ53 Carburetor Screws - Replacement for RC Carburetors  [YSF5165]

Fasteners Designed for Carburetor Service

This accessory provides a set of replacement screws meant to secure carburetor parts in model engines and carburetor assemblies. The product is aimed at addressing common wear or loss of original hardware where threaded mounts hold pieces together.

Installation is straightforward: verify sizing with your carburetor, remove the old screws, and fit the new ones until components are held firmly but not over-tightened. These screws are suitable for maintaining the position of removable carburetor elements during routine servicing.

In tuning scenarios the fasteners keep needle seats, throttle linkages and carb housings steady so that adjustments remain accurate. Always confirm correct thread engagement and part alignment before operating the engine.
