| 8653 Mr.Grylls, Hotel de France Chateauroux, Indre FRANCE. From Hs{Lord Ernest Hives - Chair}/Wst. Hs{Lord Ernest Hives - Chair}/Wst.4/MA.26.7.34. Dear Grylls, We have fitted to 21.G.IV. as you probably know a set of Philco Radio Suppressors on the sparking plugs. We have recently had complaints from a customer who owns one of the latest 20/25 HP. Chassis, that since fitting a Philco Radio set his idling performance on top gear, i.e. 5 miles per hour has been much worse. With the fitting of suppressors he is unable to idle on top gear below 10 miles per hour. Will you please try 21.G.IV sometime for idling performance on top gear and let us have your opinion regarding this question. Hs{Lord Ernest Hives - Chair}/Wst. | ||
