To obtain a higher speed following a cold start at low outside temperatures, the connection on throttle valve housing for ignition retard has been transferred from throttle valve housing to contour hose between auxiliary air valve and idle speed air distributor starting April 1978. In-between, the connection on throttle valve housing has been closed by means of a rubber cap.<\/div>\n<\/div>\n<\/td>\n
