Just got back from the shop. Was going to install a nuthin safety switch on a 91 300E and decided not to waste my time moving 2 cars to get to the hoist on this beautiful sunny afternoon. There is always tomorrow.

Broke out the 75 qnd 76 yearbooks. Book says idle speed 800-900. Set vacuum pot to 1700-1900. In drive 600-700. Turn steering lock to lock with A/C on. Should idle smoothly. Book says to adjust big nut on vac pot to increase idle, but I disagree. Year books always come out the year of car and not really tested. Instructions usually change with time. After setting up hundreds of these carbs, I keep the 1 mm distance.

If you buy a carb, be sure to get a US 1976. There are 3 carbs for 3 years. Also since they changed the 20 year law in CA, you will always need to smog a 1976. IIRC you have a float bowl vent on that model than can give you grief at light throttle.
