Default balance problem

I have a giant scale 109 in taylorcraft which I built from a Lanier kit. CG is 4" and I have been encountering big problems balancing the plane. Using the horizontal tail plane for my level I have discovered a slight warp. I am not too sure what to trust here since both give different readings on the level. The warp is slight but noticable when using the level, and looking down the fuse. I have flown other planes with simiular defects and , with a little trim, they have flown fine. So I assume, from past experience, that with a little trim there should be no issues. My problem is how can I accurately balance my plane? Since I don't know what part of the tailplane is accurate can I use my angle of incidence meter to accurately balance the plane? Also, according to the level on the rear tailplane I concidered accurate I need about 2lbs of weight in the nose to balance the plane. I have put floats on which are 47in long. They protrude about 3in past the prop, any thoughts?

According to page 29 of the manual, the wing is at zero and the stab is positive. I would use the wing. Dan.

Check page 31 for the correct location of the CG. Is that where you have it?
