| -2- 2. CONNECTIONS TO EXHAUST PIPE: The connections are very poor in design and should be entirely re-designed. The two-position admission valve is quite ingeniously arranged so that a single spring holds it in either open or closed position and serves also as means of preventing rattle. 3. CONTROL: The bowden wire control is simple and direct but not very rugged." Very truly yours, ROLLS-ROYCE OF AMERICA, INC. Per COPY NIDH:L | ||
