Struggling with high idle on 1986 240 with LH 2.2 200 1986

As far as I can tell, I'm actually able to complete the idle adjustment steps that Dave outlines. Once the IAC is disabled, I can use the set screw to get a nice low idle. It's only when the IAC is reengaged that the idle runs away.

My low idle with a disabled IAC plus the results of my smoke testing makes me believe it isn't a matter of chasing vacuum leaks at this point.
