It is recommended that the ignition timing be set at a service station that has testers from the company "Bosch", indispensable for such work. If you want to adjust the ignition timing on your own, you need a flash lamp that is compatible with the ignition system of this design. To measure the rotational speed in accordance with the instructions, connect a tachometer. For control and adjustment, perform the following work:
Accurately adjust the gap between the breaker contacts.
Connect all measuring instruments.
Disconnect the vacuum hoses from the ignition distributor.
Aim a beam of a flash lamp at the damper and start the engine. Check the position of the index pin and mark on the damper. Ignition timing data is given in the tables.
Check centrifugal and vacuum regulators. To do this, compare the indicated data when working with or without a vacuum regulator.
