How do you set the engine timing on a 4 cylinder?

To set the engine timing on a 4-cylinder engine, first, ensure the engine is off and cool. Remove any necessary covers to access the timing marks on the crankshaft and camshaft. Rotate the crankshaft to align the timing marks to the manufacturer’s specifications, typically found in the service manual. Once aligned, adjust the distributor or ignition timing as needed, using a timing light to verify that the timing is set correctly at the specified RPM.
