The proper way to set this is with a small pin that is barely visible unless you are looking for it. It is located to the left of the adjustment tower in front of the fuel distributor. To lessen the gap you need to drive this pin in GENTLY. If you go too far, you will be taking it all back apart. Set it up to no less than 1.5mm.
Have you replaced the overvoltage relay.????
