The engine has a most obtrusive roar under power from 30 m.p.h. upward. This sounds very like induction; carburetter or too early inlet valve opening. The roar does not persist on the over-run. It must drown many other faults. Induction System. It was difficult to see the type of distributor employed, the whole being boxed up in the vee. We attach curves taken in America of the car. They are not of much value as insufficient data is given. We anticipate open exhaust was used, also a sports type body as the car we tried did not seem to have a max. speed of much over 60 m.p.h. We were so disappointed with the La{L. A. Archer} Salle that we tried a Cadillac. This was a somewhat better motor car but the engine had precisely the same characteristics. The Cadillac is also £400 more than the La{L. A. Archer} Salle. It would appear to be entirely wrong to condemn this type of engine on the results obtained on the La{L. A. Archer} Salle. The rest of the car is so bad that it is difficult to imagine that they have made the best of the power unit. In any case it has infinitely less development work done on it than one 6 cylinder in line. The absence of over run vibration with the Vee eight was certainly very pleasing. We believe that we are right in saying that the Lincoln has exactly the same crank arrangement as the Cadillac and La{L. A. Archer} Salle. We therefore propose to try a Lincoln as this car has a | ||
