I recently replaced my stock carburator with a Weber DAEV 2 bbl downdraft progressive unit. The way it is designed the air/fuel adjustment screw is now located on the back side of the carb, right up next to the vw fan shroud. I tried using my offset screw drivers to turn the screw, but it was impossible. I stewed over this for a while, and the car ran good the way it was, but I was determined to adjust it properly. Sometime in the middle of the night the answer came to me – Turn the carb around for test and adjustment purposes and then re-install it correctly.
Well, I just finished doing this. The adjustment was in fact off some and now the engine runs the best it ever has for me. At least now I have peace of mind that it is adjusted properly.

I don’t know what that looks like or how it hooks up, but if you can do that to adjust it, can’t you leave it that way? Maybe you had it on backwards to start with? Maybe once it’s set right, they don’t want you to play with it anymore.
Well, the carb was not specifically designed for a VW, but to mount it so the throttle hooks up it can only be this way. You’re right, once it is set you shouldn’t have to fiddle with it again. I certainly do not plan on it.
I have this setup on my 73 Spitfire and really like it. I had the 34 PICT working pretty good on the kit car, but the Weber makes it work better. Wtih the 34 PICT I could get it dialed in just right, and then the next morning it needed more attention. The Weber is good every day.
