65LA Needle Valve Fixing Screw OS26582920 - O.S. Engine  [OS26582920]

Replacement Needle Valve Fixing Screw for 65LA

This fixing screw replaces the fastening component listed in the original part title and is intended to secure needle valve unit assemblies marked 65LA. It functions as a small but vital RC accessory that holds the needle valve in correct position to maintain consistent sealing during operation.

To install, remove the retaining plate or needle valve cover, align the needle assembly, and insert the fixing screw into the original thread until the assembly is retained without lateral movement. Take care not to overtighten so as to avoid thread or component damage.

For maintenance, the screw plays a central role in repeatable tuning by preventing the needle from shifting. Verify the screw retention after initial runs and as part of regular servicing to maintain consistent mixture adjustments and engine response.
