My friend let me borrow his incidence meter but i'm having a hard time just leveling the plane. To me it looks like the engine mount needs to be shimmed for more down thrust. I put the meter on both the stab and wing then lifted the tail untill the bubble was centered ,both read 0 incidence. I know the plane needs to be level first but how do I level it when the engine thrust line is off.. What line do I go by?
It also doesn't help that the cowl is not on straight...

Thanks
