Gas Gauge is SUPER touchy

Hey guys got another issue with the car. its not so much a problem, but a quirk that i would rather do without.

while driving the fuel gauge will bounce all over. i can sit at the light with what i can be almost guaranteed is a half tank of gas, except when i pull off of the light, the needle drops to almost a quarter of a tank. The rate of drop coincides with the rate of acceleration (as in, the faster i hit the gas, the faster it drops.) I get the same results when stopping, the needle will rise up to 3/4 of a tank. When it first happened, i thought "wow this new carb really kills my tank" but then it stumped me when the thing jumped up as high as it did. normally I wouldnt mind having a gauge this sensitive, it would keep me on edge with a full tank at all times, but after putting the new carb on, I really dont want to push being left at the side of the road with an empty gas tank especially considering how bad my mileage is these days. :toilet:

Is there any way I can test the pickup, or maybe anything i could tighten on it that would make it less responsive to level changes in the tank?

It is normal for the gas to slosh forward and backward when braking and accelerating.  Only worry about it when your rolling flat and steady for awhile.  Also, it shouldnt do that if there is more fuel in the tank..... ie fuller tank.
