Hi all,

I recently installed a new (or should say used) fuel distributor on my 1988 420SEL. While the replacement fuel distributor solved the immediate problem, I created another issue by fooling around with the fuel mixture adjusting screw. I seek to start from scratch... reset my mixture screw, then moving on to set the duty cycle using my multi-meter. I would appreciate your help.

well set up your fluke 88a to duty cycle put you leads to neg.2 positive 3 on the little connector on the left side of the engine compartment and use a 3mm allen to adjust your lambda
