I am the proud( very excited ) owner of a very nice red 72 Gt bought from "Flipper". A few days ago he was nice enough to ask the question of what would be needed to be done to adjust the carb from 1700 feet to sea level, even after the car was long gone. ( Thanks Shawn). Since then, I have done some homework and read all the forms and have adjusted the carb to " Weber Carburetor Set Up and Lean Best Idle Adjustment". Before I started the car would not idle and does not seem to have the power I think it should. I am comparing it to the wife following me home in our 92 turbo diesel passing me going up a mountain ( well mabe a hill compared to Keith's Rockys, proud of me Keith, right form) . Not cool!! Anyway, it will now idle, but the speed screw is out 3 1/2 turns from bottom and the idle mixture screw is out 4 turns from bottom. From what I have read I beleive it is lean. What do I do next? If I need to change jets are they hard to get at and if I do where could I get them? I did find a diagram of the carb to follow and I just remembered there is someone here that is nice enough to send out CD,s on a rebuild. I will see if I can get one. Sorry for rambling, must be the excitment.
Thanks Dwight.

There are some folks on here that can really help you re-jet that carb. What you'll probably need to do is take an inventory of what jets you currently have installed then they can give you advice on what you may need. it's not all that difficult.

There are two jets that are accessed from outside the carb....one on each side (one on the fender side and one on the valve cover side) ...the primary and secondary idle jets. The other four jets are accessed by taking the top cover of the carb off. Two air correction jets right under the cover....I think they have the size stamped on the top and two more jets in the float chamber that I think have the size stamped into the sides (you might have to unscrew these to see the size).

I have gotten some jets from OGTS as well as from a local VW/Offroad parts place. I have also seen places online that will sell them to you. I'm at 2100 feet so I doubt my jetting would be exactly what you want, although the one time I took my GT to the beach near San Diego it didn't seem to run all that bad at sea level.
