| contd :- -3- been necessary during the test to adjust the sockets at ball ends of carb. controls, starter carb. controls and magneto controls; this has been necessary due to wear having taken place. We are of the opinion that these should be made to exclude the dust more thoroughly. The accelerator counter-shaft also requires attention. Considerable loss of motion has occurred through these bearings having worn. Inlet pipe. We have hadno trouble with inlet pipe, it has remained in good condition. Exhaust manifold pipe and fittings. The exhaust manifold is still in good condition. We have had, towards the close of the test, an exhaust blow develop from the centre joint, and it became necessary to replace the copper asbestos washer. The exhaust pipe remained O.K. since fitting the stiffer flange to pipe as reported. Engine suspension. This has remained firm after our attention to the brackets. The rear suspension has given no trouble, bolts have remained tight, brackets are O.K. Carburetter & fittings. Examination of filters at end of run - very little dirt was found. Carburetter has not given us any trouble on the road throughout the test, but flooding has always occurred after stopping running. Very little wear has taken place in the carburetter units. Fan bracket and fan belt. The fan bracket has remained O.K. There has been no trouble with fan. It has been necessary to take two links out of fan belt. Magneto & drive. Have remained in good condition throughout the test. Dynamo. The dynamo has functioned satisfactory throughout the test. The commutator and brush gear has been cleaned once after a sligh sing had developed. Examination at finish of the test, they were in good condition. Oil pump. We have had no further trouble with the oil pressure after fitting up pump with two holes in each gear for lubricating its bearings. We still get a drop in pressure after braking, contd :- | ||
