My Friend, I've check the ignition timing by the stroboscope lamp. In idle I've got 12 degrees, but in 1000 RPM is 20 degrees, and about 2500 RPM the ignition isw so high,that I can saw it (above 30 or 40 degrees). What do You think about it?? I;ve got EZK 117 system and injection system LH2.2. The engine is B230F with Hall sensor, and the year is 1988.
