X No. 4228 Drawing No. Part List Origin. To reduce noise. Experimental Test Report. With present carburetter and air inlet, there are periods of noise caused by the air entering the carburetter which is amplified by the present air inlet. The proposed new air inlet does not reduce the performance in any way. Road Test Report. Run 3850 miles on 6-G-11. Run 2800 miles on 4-G-11. No trouble - engine is noticeably quieter.
