This is for a 300e, , get a digital volt meter, pos probe in pin 3 of the diagnostic plug and neg probe to battery negative, adjust the mixture screw to get a reading between 6.8 and 7.2 volts d.c. Remember the mixture screw has to be pushed down against a pressure spring to engage the drive, otherwise your just spinning the allen scerw to nowhere, i found it better to stop the motor do a slight adjustment then start it and take the reading, because if you push down to far on the allen key you are able to flood the motor, there`s a fine line between engaging the drive and flooding the motor. 6.8 is just lean, 7.2 is just rich. Do this properly and you`ll get a perfect idle back again.
