Kohler CV12.5S question

I have this engine on my Scag 36 inch walk behind. It runs great except its hard to start.

I have to put a drop or two of gas in the carb to start it when its cold. Once its warm it starts easily.

Any ideas? I'm not familiar with the carbuartor on this engine and unsure of how the auto prime idea works.
