This distributor uses a high-output magnetic trigger to fire an MSD Ignition Control. Accurate trigger signals and spark delivery are the responsibility of the QPQ-coated steel shaft. A sealed ball bearing and long sintered bushing hold this shaft stable at any rpm. An adjustable mechanical advance mechanism is mounted on top of the shaft. A variety of advance stop bushings and springs are supplied so you can dial in a customer curve.
