That looks good, however I like to be lean while idleing it seems to keep the engine from loading up. I also believe with it lean at idle its just starving for me to tap the accelerator, i've never had a bog with a lean idle. I'm running 2X4's Carter comp AFB's and a bog is something you have to really tune out.

Added: Your cooling system needs to be good for a lean idle, some engines will try to overheat.
