- 2 - Engine:- Runs smoothly and silently. All tappet clearances were found to be practically nil, and have been re-adjusted to 3/1000 in. cold. There is a slight oil leak from the ignition advance oil servo, which is being made good. The conditions of the cylinder bores, as regards lubrication, is good. The oiling is heavier than at the commencement; Nos. 3 & 6 being slightly heavier than the remainder. All plugs were in good condition and required no attention. The plugs on cylinders 4, 5 & 6 were absolutely dry, and slightly sooty, on n°1; 2 & 3 were just damp. Clutch & Transmission:- The action of the clutch stop is not perfect. It takes an unreasonable time (6 seconds) for the clutch to stop when really hot. The gear-box and axle are OK. Steering:- This is good all round. The control of the car is comfortable at all speeds, the only inconvenience being the effort required to hold the car on the side of a high camber road. It has a tendency to be sticky, particularly at extreme locks, and it has stiffened up recently towards the end of the day's run, despite the pivots being oiled every day. On examination, one upper bush was found to have seized on its external diameter, and has been replaced by a new similar bush. One of the lower bushes was damaged with-drawing, and has been replaced by another similar one in phosphor-bronze. There has been no sign of any high-speed steering wobbles, the maximum speed reached being about 80 miles per hour, and front tyre pressure being 45 lbs. per sq.in. On one occasion, I have had a low-speed steering wobble, at a speed of about 12 to 14 miles per hour, but have been unable to reproduce this. Brakes:- These are not up to standard. Too much pressure is required to produce the maximum braking effect. The ferodo on the brake servo has apparently less friction than the standard Halo, and this leads to the feeling that the braking power available is insufficient at low speeds. The car pulls up well from high speeds down to about 25 miles per hour, but, after that, is difficult to bring to a dead stop. The condition of the ferodo on the servo was good and clean. There were no traces of oil. The front wheel brakes' covers are inefficient, and mud and road-grit is collected, which destroys the proper action of the FWB. The rear brakes are in excellent condition, and the covers are quite efficient. The condition of the brake drums, front and back, is good. Springing:- All springs have been examined and are OK.
