Overlooking something? Fuel Starvation

I have the 650 Eddie AVS on my car and I believe I am running .104 jets in the secondary and I believe .098 jet with the stock rod in the primary. My car picks up a tremendous amount of power in the very cold weather and slows down a lot in the warm so I know its running way way too rich. I have stock type fuel pump with 5/16" lines. You may be running the very large jets to compensate for the low fuel bowl level. I never adjusted the floats in mine since I got it but I know they are both set the same side to side. I can tell you one thing my car is pretty quick with the Eddie carb on it so its definitely a good carb.

Another interesting thing is I changed my gas tank last year and cleaned out the vent tube and that made a big difference in the fuel delivery. I believe I was jetting the carb up to compensate for a restrictive vent tube and now I need to jet the carb back down. I also assume your fuel pick up filter in the tank is not clogged? Is a fuel line getting sucked closed and collapsing anywhere?
