| 18140 Secret. ----- BY.{R.W. Bailey - Chief Engineer} SJ. c. Hs.{Lord Ernest Hives - Chair} ----- E17/H.{Arthur M. Hanbury - Head Complaints} 3. 3. 25. E.A.C. ADJUSTABLE THROTTLE LEVER. ------------------------------- We send you herewith drawing LsC.2011 dealing with the above. It will be remembered that the object of this modification is to provide for the adjustment of the clearance between the throttle governor cam and the throttle lever. We now show the throttle lever clipped on to the spindle by means of a "biting in" bolt, engaging with a slack groove in the spindle, allowing for rotational movement on the lever of 5 degrees each way. The control lever now bolts on the spindle directly. /and We propose to settle the particulars of the clearance/type of throttle governor cam as soon as we get the information regarding the amount of throttle opening for the slow running of the engine.
