- While discussing ignition timing requirements: Technician A says that more advanced timing is desired when the engine is under a heavy load. Technician B says that more advanced timing is desired when the engine is running at high engine speeds. Who is correct?arrow_forwardTechnician A says that broken engine mounts can cause the fan to hit the shroud. Technician B says that missing or broken air dams can cause an engine to overheat.
