RE: starting with the choke on?
I don't see this issue on my engines Joe. After they are warm, I adjust them for proper idle, midrange, transition, and high end (sometimes a tedious procedure to get it all right), but after all this is set, it is usually set for the season, and my starting procedure works great, any engine, cold or not so cold, no restarts, and no flipping and flipping, regardless of needle settings. I feel the choke is there to get things flowing and once they do, the settings in the carb take over, whatever they are for that particular engine. As I said, if it doesn't start right away, or doesn't stay running, it is because something is wrong, and I start looking. Some of my engines like a leaner low end, like my 3Ws, but I don't start them any different and the start just like all the rest.
