I just looked at this today to see how difficult it is and it appears that all you need to do for adjustment is to turn out the set screw rather than moving the whole assembly back.
I'm also curious about any negative effects of doing this as well. Also how cold are we talking in regards to the blade sticking in extreme cold? 10*F? -10*F? More than -10*F? Thoughts on this, just curious if I'm far enough north for this to be an issue?
