This O.S. Engine OS49415010 gasket pack contains spare sealing parts specifically for GF40-model RC carburetors. The components are intended to reestablish correct seals around the carb body and throttle linkages to maintain consistent fuel and air metering after service.
Compatibility: identified for GF40 carburetor models. Fitting is simple for those experienced with small nitro or glow RC engines: detach the carburetor from the engine, disassemble the carb body carefully, strip out old gasket remnants, clean the mating faces with a recommended solvent, then fit the new gaskets and reassemble. Ensure screws are tightened evenly and confirm smooth throttle operation before running.
Tuning effect: sealed gaskets prevent air leaks that cause idle instability and unpredictable needle adjustments. Swapping out collapsed or damaged gaskets is a standard troubleshooting and upkeep action when inconsistent running or flange leaks occur.
