"The best price I could find where I live in Australia was $1000, including fitting them on the car and synchronising.
Now maybe I am a spaz but I bought kits and tried doing them myself but it did not make them work any better as the bodies were warped. So Ray, how does a home handyman get all the mating surfaces flat? Do you get a big belt sander and gently sand them? How do you make sure you are doing it perpendicular to the axis?"
Thanks for asking. Just today as I was researching a Mercedes 190 factory shop manual in the public library I was thinking about this forum. My thought was that, except for "rumb" (Dan) in Colorado, there seems to be an absence of exchanging hands on information on how to actually do stuff. The emphasis seems to be on who to pay to do stuff.
I don't have a clue what kits for your carburetor(s) cost. I do know that carburetors are stone age devices that any motivated amateur can service, and even improve, very easily. Both factory service manuals and carburetor kits contain very detailed instructions on removal, disassembly, cleaning, reassembly and adjustment. As with any endeavor, your first efforts will be slow and some steps may have to be redone. However, as experience accumulates and confidence increases you will be able to do literally anything on your car(s).
Dan is ecactly right on how to true the flange surfaces. I would only add that a machined surface like a drill press table, table saw table or any other surface that checks out flat with a straight edge will work. Perfection is not necessary because carburetors are installed on manifolds with gaskets. All you are trying to do is correct warping cause by overtightening. If you do as Dan suggests you won't deviate from a perpendicular with the throat axis to any significant degree.
I'm a newcomer to Mercedes, having just delved into my wife's 1961 190SL. I've trolled this and one other forum looking for "how to" information, mostly to no avail. For example I now have to pull the gas gauge to figure out why it doesn't work, and quit working long before my wife parked it 20 years ago. Access to the gas gauge is blocked by some switches below it that have bezels that seem to require some special tool for removal. I hope to be able to solve the mystery of what that special tool is so I can make one.
Drew, I can guarantee you that if you break free of the feeling of being stuck with the services of "professionals" you will benefit in getting vastly better results from the work that you do, you will save a ton of money and you will have the rare satisfaction of saying "I did that" when you mash down on the accelerator pedal and your car leaps forward.
