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

Secure Carburetor Screw Replacements

This RC-scale accessory supplies spare screws designed to fasten carburetor components in model engines and carburetor assemblies. The set addresses wear or loss of original fasteners and suits locations where threaded mounting points hold carburetor parts together.

Fitting is simple: check the screw dimensions against your carburetor, remove the old fasteners, and fit the replacements until components sit firmly without over-tightening. These screws help preserve alignment of removable carburetor parts during routine service.

When tuning, the screws help keep needle assemblies, throttle linkages and carb housings stable so adjustments stay consistent. Always confirm thread engagement and part alignment after fitting and before running the engine.
