PVC Valve Question with Weber 38

I replaced my old PVC valve with one from the local shope (off the rack not specific to my vehicle) and I had to retweak my settings. It appears the new one lets less air to pass and I had to adjust my carb. My concern is that with my Weber 38 I want to stay as low as possible on my idle speed screw (close to 1/2 a turn is desirable), but with the new PVC I have to turn it to about 1 turn out to get the correct idle speed. I didn't realize that PVC valves where that different. Could someone school me on what's going on. My guess is that I'm going to have to order an OEM one.
