Not an expert on carbs by any stretch of the imagination but couldn't get this thing to work even remotely close to right so I order a kit and tear it down, Weber 34 adf, I find 120/135 mains, 145/180 air, f20/f5 emulsions and primary idle I have not got out yet but secondary is a 90, I'm thinking idle jets are a gonna be a bit big and not real sure on the emulsion tubes, any body have some expertise here ?
Not sure it matters a lot but most of my driving would be below 1000 feet elevation
Guess I should add it's on what I believe to be a stock 1978 spider 124 with what I think is 1756 engine

Re: Another carb question
Have you read Brad Artigue's online guide to maintenance? Even better bought his book on Amazon?
That should give you pretty much everything you need, plus the right number to identify your engine.
Alternatively - post pictures and we'll take a series of fairly educated guesses!

Re: Another carb question
Those jets numbers sound weird. The primary idel jet will have the most to do with idle and low rpm running, so that's the
important one. Likely should be 50 or 55 on your car.
