Ok guys here is the latest, I was not able to change the tank as the one I was going to use leaked and I did not feel like assembling another one, but the one thing I did not mention is that I had a Tetra shut off valve in the fuel line that fed the carb. I replaced that fuel line and removed the valve well guess what, the bubbles are gone. It ransitions well to 9100 then I backed it off to about 8800. I then did the 4000 test and it was fairly stable. But the idle is still not great, I can idle down to about 2800-3000 without the igniter and it will hold it for atleast a minute before it starts to slow up and die. I was running out of daylight and had to stop but I think if I keep the igniter on and get it down to 2500 or so I should be able to adjust the bottom end, right?
