We cannot judge Bentleys on one car and are trying to obtain further information. (4) We have never been able to prove that chassis vary from one to the other for this complaint. (5) Flywheel whirling exists. So far we have been unable to connect it with the trouble. (6) We agree whirling on P.II seems rather worse than on P.I. (7) Since balance weights have no effect nor has a cast iron crankcase on the 20 HP, we do not think booms are connected with crank-chamber deflection. We are quite certain that if we went back to P.I engine mounting, we should not be free from booms. We have tried it more than once. | ||
