Engine Maintenance
Please clean the fuel filter in the RCGF Carburetor periodically. Failure to do so may
result in miss-calibration of the needle adjustments. In order to do this it is necessary to
remove the Phillips head screw which secures the carburetor filter cover and the
carburetor filter gasket. Use only carburetor cleaner to clean the opening around the filter
