“2. Engine starts and stops after a few Revs,
“3. Irregular sound of exhaust—machine will not climb,
“4. Popping back of Carburettor,
“5. Overheating and knocking,
the Instructor is to set up faults for the students to remedy.”
He is given ideas for nearly fifteen ways of producing the symptom “Engine won’t start.”
“It is suggested that the Instructor should insert a piece of paper between the platinum points in the little magneto, or fit a faulty contact breaker with a stiff rocker in the big magneto, or smear segments and outside of the distributor with a little dirty oil; if he desires to queer the plugs, he may insert one with its gap closed up or bridged with dirt or with a cracked insulation. To produce symptom No. 2, he may insert a punctured float in the Carburettor or insert a piece of rag in the passage between the float chamber and the jets, or block a cock under the Autovac. Or in order to produce an irregular sound in the exhaust and to make the machine refuse to climb, he may remove the roller and pin from one or more inlet valves; or place two faulty plugs in the engine. To make the engine overheat, he is to insert an extra link in the Radiator Fan Bolt, open the Air Slide, or start a leak in one or more of the water outlet elbows. He may make the engine tap and rattle by adjusting the valves with abnormal clearances, and so on with the number of other defects, which each student in turn is to be called upon to diagnose and remedy.”

“Before beginning a Battle Practice, the following points must be seen to:
