YS Engine YSF5165 Carburetor Screws FZ53 replacement screws for RC carburetors  [YSF5165]

Carburetor screw replacement and maintenance

This RC-scale accessory provides replacement screws intended for securing carburetor components in model engines and carburetor assemblies. The item addresses basic wear or loss of the original fasteners and is used where threaded mounting points hold carburetor parts together.

Installation is straightforward: confirm fit with the carburetor assembly, transfer or remove the old screws, and install the replacements until components are held securely without over-tightening. These screws are intended to maintain alignment of removable carburetor parts during routine maintenance or tuning sessions.

In tuning contexts the screws act to keep needle assemblies, throttle linkages, and carburetor housings stable so that adjustments remain consistent. Always verify thread engagement and component alignment after installation and before running the model engine.
