With regard to your memo. on the above in which you say you are demonstrating that the governor should be made tw give a preliminary advance from nothing to 250 revs. of the engine, we have always known and appreciated that the engine requires a preliminary advance of the ignition point after being started. This point was considered when designing the governor and it was decided by Mr. Royce that it was not practical to expect a simple working governor such as we have adopted for Goshawk II to perform this initial advance, but that this was to be obtained by the hand lever on the steering column such as is done on every other car. A simple working governor has very little power unless it is going at a good speed and cannot be expected under all conditions of working to definitely control the ignition say from nothing to 250. r.p.m. It might be a different matter if we had a governor working on a relay system.
