X149J. 1 5/8 S.U. CARBURETTER TO NO.1187. This carburetter gives 13 B.H.P. more on the standard 20/25 HP. engine than the existing carburetter. It also gives better slow running and is free from banging in the silencer. The starting, arranged as shown in this report, appears to be satisfactory from road tests.
