Refitting

that the mating faces of the valve and air
cleaner are clean.
10 On completion, start the engine and check that the idle speed is stable, and that there are no air leaks. Warm the engine up to normal operating temperature, then switch on all available electrical loads and check that the idle speed is maintained.
