| R.R. 235 A (400 T) (S.C. 536. 15-2-16) G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 1546. ORIGINAL To EH. from R.{Sir Henry Royce} C. to BJ. X.682 Re - Ignition Plugs. Will you kindly send us a dozen ignition plugs for 7-CA, and we will return to you those we have that are bad and dirty. Could you tell us how you would clean these plugs? X.3129 We have removed the Remy and fitted our own, and the engine is now very much more reasonable to start and run slowly. The fibre in the magneto swelled and made the contact maker always open. We have filed and adjusted it so that this ignition is very good. Also the air valve moves much too quickly - please send a very slow moving one. X3225 We put in the new needle valve in the float feed which worked perfectly right away and could not be made to fail. We have only run the car 30 miles in 2 months.
