For what it's worth and y'all know the answer to that one. But I quit opening the choke at all when starting cold last year. It ticks over and idles smoothly from the "getgo".

Prior to that, with choke open it'd fire right up, but wouldn't settle down to a smooth idle for a few minutes. Granted there's many variations off the same basic setup, or "your results may vary".
