Wraith III Engine Controls. LeC.5633. In order to make it easier to assemble the engine in chassis with the steering box in position, it has been suggested by the Experimental department that the two studs which hold the throttle control shaft to the facing at rear of clutch housing should be changed to set screws. As it will not be necessary to remove these set screws very often, we agree that this should be done. Will D.O. please alter the details to suit. The tapped holes in crankcase need not be bushed.
