Alas, the position of the various ports on various carbs is a very carb-specific matter :-( Since I have not owned a bus like yours, I can't say for sure which port does what on your carbs. > Steve, I guesss first I need to know whether port or manifold connects > to the advance on the dizzy. Vacuum advance connects to ported vacuum. > I really do not want to buy a vacuum guage. Maybe I will have to. Ray, I strongly suggest you do! They have all sorts of uses on a bus. At this point in time, my recommendation is that you go out and buy a mity-vac at your flaps. They are less than $20 and include not only a gauge, but a vacuum pump. The vacuum pump is very useful for bleeding your brakes, the gauge will let you tune and check your engine. A very useful all-'round tool! > Anyone have a stock dual solex setup that can take a look at there > carbs and dizzy for me? The ideal solution!!! Please, someone with stock dual carbs, go and have a look! I would go out to Springfield and take some pics of Barry's '72, but I promised my boss I would come in to work today, even tho it is a holiday.

Steve and List Volks, O, now my head hurts. I was feeling very comfortable with the top port (on the right of the carb) attaching to the advance on the dizzy. And the other vacuum port attaching to the lower one (on the left of the carb). My concern all along is that there is this other port, which appears to be vacuum and is currently capped off, below the air cleaner assembly on the thing that connects the two carbs. Now I'm not sure that even the advance vacuum line is correct. Steve, I guesss first I need to know whether port or manifold connects to the advance on the dizzy. I really do not want to buy a vacuum guage. Maybe I will have to. Anyone have a stock dual solex setup that can take a look at there carbs and dizzy for me?
