| -3- Contd. Once the correct mixture for silencer explosions is obtained on a Silver Ghost, the explosions are equally as violent and numerous as on a Phantom under similar conditions. It was noticed on a Silver Ghost that to produce explosions a richer mixture is required at slow speeds than at higher speeds; the higher the coasting speed, the weaker the mixture required. This was not found to be the case on the Phantom. Hs{Lord Ernest Hives - Chair}/A.J.Lidsey. | ||
