Erratic timing on your Datsun 210 could be caused by several factors, including a worn or damaged timing chain or belt, which can lead to incorrect synchronization of the engine's components. Additionally, issues with the ignition system, such as faulty spark plugs or a malfunctioning distributor, may contribute to timing problems. Vacuum leaks or issues with the fuel delivery system can also affect engine performance and timing consistency. Lastly, an improperly set ignition timing or a malfunctioning electronic control unit (if applicable) may lead to erratic behavior.
i suggest changing the distributor. i had erratic timing for a while, during cruising speed the emgine would chug here and there. One day I decided to replace the distributor cured my erratic timing, and stopped the chugging.
What is the process for installing a new timing chain for a 1980 datsun 280zx?

Yes, it is possible to change the timing chains on a Datsun U20 engine without removing the engine from the vehicle. The procedure typically involves removing the front timing cover, which may require removing other components such as the water pump and oil pan. Careful alignment of the timing marks is crucial during reassembly to ensure proper engine timing. Always consult a repair manual for detailed steps specific to your engine model.

To set the timing on a Datsun B210, first ensure the engine is at operating temperature and then turn off the engine. 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 its hold-down bolt and rotating it until the timing light indicates the desired timing mark aligns with the pointer. Once set, tighten the bolt and recheck the timing to ensure it is stable.
That means the timing chain and gears are worn out / to loose.
To remove the timing chain on a Datsun 620, first, disconnect the battery and remove any components obstructing access, such as the radiator and front timing cover. Align the timing marks on the crankshaft and camshaft to ensure proper timing during reinstallation. Then, remove the tensioner and guide, followed by the chain itself. Finally, carefully take off the sprockets, if necessary, to fully detach the timing chain from the engine.
