How to set breaker points?

Directly. Less gap=more dwell
Maybe somepeople don't know what dwell means.


""In an ignition system, "dwell angle" refers to the period of time, measured in degrees of camshaft rotation, during which the contact points in a distributor remain closed, allowing the ignition coil to charge up before the spark is created; essentially, it's the duration of the current flow through the primary coil of the ignition coil.

Key points about dwell angle:

• Function:
  The dwell angle needs to be sufficient to allow the magnetic field within the ignition coil to reach full strength, ensuring a strong spark when the points open.
  
  
• Measurement:
  Dwell angle is typically measured in degrees of distributor rotation on a mechanical ignition system. ""
