[Conrad W Peden]

Is it a progressive carb? Two barrels, one smaller than the other, and the small one opens when the large one is at about 3/4 throttle.

If so say bye-bye. I had this carb on my '72 and the accelerator pump got a hole in the diaphram. Good luck finding a diaphram for it. These thing seem to be obsolete. And if a single two barrel carb was good enough for these engines Porsche would have put one on them not two(1.8's?)or FI.

If you want to go FI get it. If you don't, I have been using dual Dellortos for ten years with no trouble. As soon as I put these on my car and got them jetted and adjusted properly the car seemed to have twice as much power alot higher into the revs.
