How do you set the ignition timing on a 1400 Nissan?

To set the ignition timing on a 1400 Nissan, first, ensure the engine is at operating temperature and idle speed is correct. Locate the timing marks on the crankshaft pulley and the timing cover, then use a timing light to check the current timing. Adjust the distributor by loosening the securing bolts and rotating it until the timing mark aligns with the specified degree (refer to the service manual for the exact number). Finally, tighten the distributor bolts and recheck the timing to ensure it's properly set.
