You didn't say where you got your Webers. If you got them from JAM then they will have the correct jetting for your setup. If not, then the jetting might be suspect. I got mine from a company in New York (before I heard of JAM) and they were jetted way too rich. I had them re-jetted by a local Weber expert. I think I have the jet sizes at home, if I do (and can find them) I will send the information to you.
