Eddy 1405 tuning advice
Now, this bears sayin too........Although the idle air screws don't affect anything in the power circuit, the same cannot be said about the metering rods affecting the idle circuit. They DO have some influence there. Not much, but they do, so keep that in mind. In other words, when you go to a smaller (richer) metering rod, you will likely have to readjust the idle air screws, since the metering rods have some effect at idle, believe it or not.
