Sidgreaves - MD} E.{Mr Elliott - Chief Engineer} By.{R.W. Bailey - Chief Engineer} ___________ Kingsbury - 2.4.37. 25/30 H.P. Cricklewood are having difficulty in keeping owners satisfied with regard to the slow running and over-run explosions in the silencer. The slow running is not good and is too critical. To obtain moderate slow running the jet has to be made on the strong side, which in London traffic soots the plugs up. Rm{William Robotham - Chief Engineer}/GWH.{George W.
