Generator question - let carb run dry or keep it wet?

On ATVs, generators, etc. I've always run the carb dry or drained it. Occasionally will make moderate term exception for products with gravity feed fuel flow where the bowl will not dry out.

Think in general, drain it, run it dry. Don't let gas sit in tank for a long time. Two strokes using premix seem to be less sensitive to these problems due to the oil residue.
