| (5) Butterfly Vlave Squeaks. This takes place when the engine cools down and the butterfly valve requires refitting. I pointed out that this was not a general fault, and in this case could be cured. Clutch does not stop quickly enough. This is quite up to our normal standard, Mr. Summers, however, states emphatically that in his case he requires special attention, as for fast use he requires the clutch to stop quickly. He was able to effect such adjustment on his "Silver Ghost" which cannot be done on this car. I could not give him any hope. Rattle from Gear Box This could not be clearly demonstrated, but I suggest that the trouble is with the starter jaw clutches which do not disengage properly. Oil pressure failed on one occasion but went allright again Mr. Summers asks that the oil system and relief valves should be thoroughly cleaned out and inspected. Tappets noisy. He complained that he found No.2. exhaust valve had no clearance, also that there is a click from No. 10 tappet which he is no able to cure by adjustment. Water leak from engine. Trouble has been experienced with the rubber joints from the engine to the radiator. This he has so far been able to cure by fixing closer fitting rubber joints. Lubrication of spherical actuating levers to front wheel brakes. Mr. Summers insisted that lubricators should be fixed on these joints as at present the lubrication is not satisfactory, and it is a big job to take them to pieces to lubricate. Brakes Servo Grabs. The brakes are rather inclined to thump and on the "too effective" side. Mr. Summers points out that St's car is a good sample in this respect. I certainly agree that his point is quite good. reasonable Carburetter air valve has given trouble with sticking. He has definitely increased the clearance between the air valve and the piston, and requests that the "damping" of this air valve should now be re-adjusted, as it is not now satisfactory. He was able to demonstrate to me successfully, however, that the clearance between thepiston and the air valve was quite different hot or cold. CONTINUED. | ||
