I mean if you can't get the car to idle under 1200rpm then something is either wildly out of adjustment or just plain broken. Vacuum test first.
Also is the vacuum still hooked up to the deceleration valve? I'd disconnect and cap that line first. When that fails it can lead to a high idle and maybe screw up everything else you're trying to adjust for. It wouldn't cause a lean condition (downstream of metering plate) but at least you could get the right rpm at idle to check stuff.
