Question

if required during the initial engine break - in period, run the engine at ______ (1200 - 2000 rpm).

a. start

b. stop

c. low idle

d. high idle

Explanation:

During engine break-in, 1200-2000 rpm refers to a higher idle speed than standard low idle. Start/Stop do not describe a sustained rpm range, and low idle is a lower speed range. High idle matches the specified rpm range for this break-in step.

Answer:

d. High idle
