Default Not a weight problem

Thanks again.
It can not possibly be a weight problem. You can fly with several gallons less fuel in one wing than the other and it is hardly noticeable. Once you have enough fuel imbalance to notice, the aileron trim takes it right out easily with very small adjustment.

The trim adjustment to fix a "heavy wing" is usually much greater. So it can not be from a physical weight difference.

What Carl said is right. The three biggest culprits are incompletely formed trailing edge bend, height of the aileron upper surface with respect to the wing upper surface, and warping/drooping of the fiberglass wingtip because it was attached with the ailerons out of rig.

You richen the mixture right? It makes sense so you do that and the problem doesn't go away so then what do you do? You increase the idle to overcome the rough idle because of the pour mixture . Although sometimes that would work or partially the real problem was that you had a vacuum leak if you find the vacuum leak setting the mixture correctly will be no problem . Do you see what I'm saying? We are turning up the idol because we can't find the vacuum leak . I WANT FIND THAT VACUME LEAK! ( metaphorically speaking )

Or, they secretly put in a cam that has increased valve overlap and the decreased vacuum and allows the power valve to open and richen the mixture through the power valve channel restriction in the metering block that have been opened up to cover the up the lack of fuel running through the too small main jets because they installed a too large of a max CFM carb
