| - 2 - Mxl/T7.7.26. 1. Clutch Jaggers badly. This may possibly be dealt with by the oil and paraffin method. Br's method of dealing with this, by bedding and trueing up of the faces evidently does not remain satisfactory. 2. Power poor. This car was well up to standard when on test. 3. Smoke from Exhaust. This is rather inconsistent if due to overoiling in view of the exceptionally good oil consumption ile. 1600 m.p.g. 4. Tappet noise. For your information this may be due to slight piston knocks, but I think perhaps it would be inadvisable to inform Bt.{Capt. J. S. Burt - Engineer} of this. 5. Steering slack. This is very difficult to diagnose unless the actual car can be tried and examined. 6. Heavy clank in transmission. This also is very difficult to diagnose unless the actual car can be tried and examined. As Bt.{Capt. J. S. Burt - Engineer} states in his report that CWB is trying the car for these specific points which he considers make it unsuitable for trials purposes, we shall no doubt have an opportunity of trying it for ourselves. Springing. This is referred to in point (a) Boiling. This car was quite satisfactory on test, and passed the water consumption test on the dynamometer without any trouble. Hs.{Lord Ernest Hives - Chair} has already reported his views on this feature. Involuntary stops. A special new accelerator pedal was fitted by 'N', and in this case it appears that the split pin was not correctly fitted. We assumethat the standard Klaxon Horn switch platinum points are referred to, and not the Bosch Horn switch, or Eural Steering wheel switch which are fitted to this car. This is the first report we have had of the points in a switch coming adrift. contd:- | ||
