What Are You Doing To/With Your Car Today?

Let me guess... that AVS-II has a big "bog" off idle ...or actually any time you punch it? That's how mine is. I tried to follow their technical advice, but the color springs they supply do not match their chart. It's 100% trial & error then. Still not right.
My chief complaint was not about any bog but the fact that my wide band showed the mixture was too rich through the range. I looked at the tuning chart that came with the book and called Edelbrock. Their tech informed me that they do not have the tuning charts for the AVS2 complete and my book chart was for the thunder series carburetors which do not apply to our new carbs. He recommended a rod change but was not advocating a spring change. When pressed he said I could try the pink spring and the entire spring kit is only about $10 so I ordered it as well. The tech said to make very small changes and to read the plugs as a more accurate way do determine rich/lean. My plugs look perfect but I know the mixture is rich through the range so I will make the rod change. They are supposed to have the tuning charts for the AVS2 complete and released soon. My bigger problem is my damn valve train geometry and getting it correct.
