Help with Carb Issue!

I don't see anything in your posts about manifold vac , are you sure you have the right power valve's in it ? mine were 6.5 and fine for 3 years but engine wear dropped the vac at idle a little and they became too big causing idle problems at the lights and a rich condition , replaced with the 3.5s that come in the quick kit and they were too small causing it to lag at mid throttle when they opened late , get a vac guage and see what you actually need .
