The correct setting for the points in a Datsun should be between 49 to 55 degrees of dwell. This is really the best way to do it, so grab your dwell angle meter & set the points to 49 degrees & as they wear, the figure will move towards the 55 degree figure.

Once the points are correctly adjusted, then set the timing & you're set to go. Check them at about 1,000 miles as new points wear quickly, then again at about 5,000 miles for maximum return on your tune up.

You will find that the $10 to $20 spent on a service & repair manual will save you a lot of wasted time money & effort. It is the best bargain that you will ever buy for your car.
