Tune-Up - 4 CYL: Distributor

All models use a Ducellier single pick-up breakerless distributor in conjunction with an AC Delco coil and transistorized amplifier module. The only adjustment provided is for air gap between the reluctor and pick-up coil in the distributor. Measure gap using a non-magnetic feeler gauge.
