| -3- EP{G. Eric Platford - Chief Quality Engineer}2/H23.5.25. (12) Contd. get into the same condition as the water pump drives did on the early 20-HP chassis. (13). Battery ignition, make and break points burning. This has already failed on Trials car 29-MC. Similar trouble has also been experienced with chass s on test. I also understand that Hs.{Lord Ernest Hives - Chair} had similar trouble on experimental cars. (14). Exhaust cut-out Bowden wire control. This has been criticised as to whether it will stand general service use. (15). Carburetter petrol drain pipe. This at present appears to drain on to the exhaust pipe. it has been suggested that this pipe should be definitely clipped to the crankchamber, so as to make sure there is no danger of petrol from the carburetter dropping on the exhaust pipe, which is underneath the carburetter. (16). Oil consumption of the engine. This is a point which I understand is having Experimental Dept. attention, but our experience also leads us to query tendency of ignition plugs to oil up, smoke from exhaust, rapid forming of carbon in combustion chamber. (17). Accelerator pedal. Too much movement and awkward for driving. (18). Low tension wire leading to the actuator starter mechanism. It has been suggested that more adequate protection is required for this wire, i.e. where it enters the main wiring tube on the frame and where it enters the actuator mechanism itself. (19). Earth connections of main wiring system. We have had a case of a good connection at this point being doubtful. It has been suggested that this should be made with a definite spring washer adjustment so as always to obtain more definite contact, even though the bolt or nut may become loose. (20). Battery wires. It has been suggested that the lead wires to the battery may be made longer, so as to accommodate customers who insist on fixing their batteries in the frame. (21). Range of shutter control insufficient. It appears necessary at present to sacrifice the full closing position in order to obtain the full open position. The controlling of the best position for the shutters to obtain satisfactory water heating also appears too delicate, and the full working temperature range is controlled by two or three notches only.
