) If normally compressed engines are operated with fuel uder 98 RON (min. 88 MON), adjust firing point in direction of „retard” and match to octane rating of fuel used. The reference value for this adjustment is: set firing point back by 1\u20142 \u00b0 crank angle per 1 RON. Max. setback should not exceed 6 \u00b0 crank angle. Attention!<\/strong><\/div>\n
Taking firing point back is considered an „emergency measure”. <\/strong>Reduced output and increased fuel consumption will result. In addition, the engine should not be fully loaded. As soon as fuel with specified octane number is available, set again to full advance.<\/div>\n
) To set firing point, pull off both vacuum lines for ignition adjustment. 3<\/sup>) Switch off air conditioner, automatic transmission in position „N” or „P”.<\/em><\/div>\n<\/div>\n<\/td>\n

Taking firing point back is considered an „emergency measure”. Reduced output and increased fuel consumption will result. In addition, the engine should not be fully loaded.
