So, not trusting that I was using DanH's method correctly (http://www.vansairforce.com/communit...60&postcount=2
), I decided to mount the prop, level the spinner plate and laser it, bisecting the spinner plate (convenient alignment holes provided!). Sure enough, the left inlet is quite a bit larger than the right.
Left side: 10/32"
Right side; zero trim
Black lines were my first try on the floor; the laser pretty much confirms it.
However the overlap on the left side is pretty small .. 1/16" ish. Looks like I'll need to extend cowl edge a bit.
