| contd :- -2- As regards the effect of the brake causing the high speed wobbles. Was this ever noticeable on the std. 40/50 HP. cars? We should also like more information about the weak carburation picking up. This may be due to the fact that of the exhaust choke valve sticks open there will not be sufficient heat to the hot spot. Clutch jaggers. When we send the new pistons we shall have to get this clutch right. You mention in your note that the oil consumption is slightly improved owing to removing the relief valve. We should say that the probable difference in the oil consumption is due to the fact that you have changed all the pistons. Will you please let us know why you think the oil consumption has been improved by alteration to the relief valve. Hs.{Lord Ernest Hives - Chair} | ||
