-2- EPY3/MH.{M. Huckerby}22.10.34 <handwritten>long run</handwritten> I suggest an inspection should be made of the front axle anchorage, as this appears to be <handwritten>giving</handwritten> trouble according to GWH{George W. Hancock - Head Chateauroux}'s 10,000 miles test report. Inspection should also be made of the brake movement, as this may have been re-adjusted by N. One has the feeling that the servo brake is not running true, as this is noticeable by the brake pedal movement when taking up the end clearance in the servo. The front axle 'judder' becomes very bad and was brought <handwritten>home</handwritten> by ordinary application of the brakes at 45 to 40 m.p.h. <handwritten>They do not</handwritten> require any 'trick' driving, <handwritten>& to produce</handwritten> The engine during the latter part of the run entirely failed, and it was ascertained due to faulty petrol supply. Disconnecting the petrol supply from the petrol pump to the carburetter showed that the petrol pumps were not functioning. One pump failed to work entirely - in fact current was passing through same continually and causing it to overheat; the other pump had apparently been working and stopping. Cleaning of the contacts appeared to make this pump work better, but on continuing the test it still had occasional failures. The electrical mechanism appeared to be in a very poor condition, and it was found that by reducing the stroke of the pump it became more reliable. This was done by re-fitting and setting of the contact points (temporary), and I was then able to get both pumps to work. Although in carrying out this job (on the road-side) the ebonite supporting the terminal was damaged, no further trouble has been experienced with the pump. It is necessary, however, that the pump should be properly overhauled and that the definite cause of the trouble should be ascertained, as it certainly | ||
