| -2- (7) Do you have any trouble with the flap valves in your exhaust pipes for by-passing heat to the hot spot ? What material do you use for this valve and what is the material of the spindle ? (8) Have you had any case of flywheel flutter on this unit ? Do you find that if you reduce the width of your flywheel bearing cap or decrease the diameter of the crank at this point, you get flywheel flutter ? I should be very grateful for any information that you can give me on these points, and would be pleased to answer any questions about our own products. Yours sincerely, FOR ROLLS-ROYCE LIMITED. | ||
