Thanks Cafeen for reply, I will now explain what I did. I kept the fuselage on a level surface, now I leveled the Fuselage with Robart Inceidence meter (fixing it on to the F1 and F2 former on the top middle position).

I mounted the Robart Incidence meter to the wing tips and made it 0 degree incidence as per plans and pinned it . Same with the stabs. Engine location was as per plans at 0 degrees but traced from plans.

Problem or you can say some confusion:

After finalising incidence I had removed the fuselage from the orignal leveled position and had placed the landing gear. Now, after the landing gear got fixed I releveled the fuselage for a recheck, my position of level was changed on both wing tips and the Stab. Now to recheck what I did was to fix the Incidence meter over to the wing tip again. I level it to 0 degrees the same way I leveled the fuselage . After releveling on the wing tip my readings over both wing tips and stab are same as per orginal settings done earlier. When checked the engine thrust is + half degree.

According to me I feel I have done correct but is there any way else to be 100 percent sure what I have done is right?
