Watch how it drifts when the station cools off or heats up. While the VCO may lock between, say, 20 and 40, the book recommends 38uA so it has some room to swing. You can adjust the tuning and see how high and low you can go before the green LED goes out, then tune it in the middle. As long as it stays locked, you're OK.
Long-term drift should be 2-4uA. If the tuning is erratic or the meter jumps around as you slowly adjust the tuning slug, you'll have to pull the VCO, pull the tuning slug, clean all the metal filings off the threads and inside the VCO, put it all back together, make sure the thin nut is tight so the tuning slug requires a bit of erfort to tune, and readjust it. Everything should tune smoothly with no jumps on the meter.
