3-37. When the starting motor of a gasoline  engine  turns  but  fails  to crank the engine, the trouble is usually  found  in  the 1. drive  assembly 2. engine  timing 3. fuel  system 4. ignition  system 3-38. Which of the following problems can result  from  overpriming  a  gasoline engine? 1. An  overheated  engine 2. An  inoperative  fuel  pressure gauge 3. Stuck  piston  rings 4. Corroded piston crowns 3-39. You are checking for trouble in a fuel system that has a wobble pump. If the pump feels or sounds dry, where is the trouble probably located? 1. In  the  carburetor 2. In the line to the fuel pump 3. In the fuel pump 4. Between the fuel pump and the supply  tanks 3-40. If a gasoline engine with a battery-type  ignition  system  fails to stop, what is the most likely cause? 1. The  switch  contact  points  are open 2. The  ground  connection  is  open 3. The  switch  contact  points  are closed 4. The battery terminals are burned 3-41. Oil  purifiers  are  designed  to  give maximum  efficiency  when  you  operate the purifier at what limits? 1. Minimum  speed 2. A speed determined by prevailing   conditions 3. A  speed  between  minimum  and maximum  and  below  the  rated capacity 4. Maximum  designed  speed  and rated  capacity 3-42. Most oil used by the Navy can be heated  to  what  maximum  temperature without  damaging  the  oil? 1. 195°F 2. 190°F 3. 185°F 4. 180°F 3-43. When  the  military  symbol  9250  lube oil is to be purified, it should be heated  to  what  specific temperature? 1. 140°F 2. 160°F 3. 175°F 4. 180°F 3-44. The size of the discharge ring used in a purifier is determined by which  of  the  following  factors? 1. Viscosity  of  the  oil 2. Moisture content of the oil 3. Sediment content of the oil 4. Specific  gravity  of  the  oil 3-45. What is the best method of determining  the  efficiency  of  a purifier? 1. Oil  clarity  check 2. Oil  analysis 3. Batch  process 4. Bowl sediment check 3-46. Which  of  the  following  corrective measures  should  you  use  to  reduce the  number  of  engine  governor difficulties? 1. Reduce  the  engine  speed 2. Increase  the  engine  load 3. Use clean oil 4. Adjust  the  fuel  linkage 3-47. When  installing  a  new  or  overhauled governor,    which  of  the  following governor  components  should  you adjust? 1. Governor  linkage 2. Compensating  needle  valve 3. Speed adjusting screw 4. Speeder  spring 21
