| -3- (2) We wish to use the minimum of damping on the air piston so that it will fall quickly on closing the throttle and therefore be in the condition to permit quick opening up again. R.{Sir Henry Royce} will supply us with expl. schemes for balanced air piston. (3) The carburetter should be modified to take the slow running fuel from the base of the diffuser. When the acceleration is as required we shall turn our attention to the finer points of metering by means of the taper of the air piston needle valve. Ha/L. Swindell. | ||
