SUMMARY OF TEST. The tests taken in the attached reports were made with the object of proving that the choke valve in the exhaust could account for over-heating troubles. It will be seen from the results, both on the road and on the bench that even under the worst conditions the difference can only be very slight, under normal conditions it would not be measurable. We are making tests to measure the effect of detonation, but if detonation occurs it is always audible. Hs.{Lord Ernest Hives - Chair} | ||
