With my choke, "half on" means it doesn't do anything yet. When you move the choke lever (from "off"), about halfway you will feel the resistance increase, that is where the choke effect starts.

I always start with full choke. After it starts, turn it down a bit to reduce the high idle revs. Drive off and gradually reduce it more, until it's completely off, usually within a mile.
