Leaded fuel
1. In the case of a contactless ignition system, the static ignition timing cannot be checked. However, if the distributor was installed correctly (see section 17), the ignition must be adjusted accurately enough for the engine to start and continue to run.
2. Setting the dynamic ignition timing using a stroboscopic lamp is described in section 8, paragraphs 10,11 and 12. Keep in mind that the distributor is not secured with a clamping screw, but with two nuts. When checking/adjusting ignition timing, the precautions specified in section 15 should be observed.
3. The contactless distributor does not require checking/adjusting the angle of the closed state of the contacts.
High octane unleaded fuel
4. The engines on the models in question are designed to run on high-octane unleaded fuel, but the manufacturer recommends that the ignition timing be adjusted as follows.
Carburetor engines
5. If the engine knocks when using high-octane unleaded fuel, the ignition timing should be reduced by a maximum of 5 degrees. (see section 8, paragraphs 13-19).
Injection engines
6. When using high-octane unleaded fuel, the ignition timing should be reduced by 5°, because Otherwise, this fuel may cause inaudible detonation at high speeds, which can cause engine damage. The regulation procedure is given in section 8, paragraphs 14-18.
