RE: starting with the choke on?
It is probably best to use a procedure both that works and one that you are comfortable with. Personally, I am comfortable with and strictly adhere to this procedure. I always follow the same steps to keep from forgetting to, for instance, close the choke. However, on a cold engine, you would flip and flip with no hint of firing in this configuration, if the choke was open all the way, a tip something is amiss. These steps have my cold engines running in 4-6 flips total, always. As noted already, the engine simply will not run more than a second or two fully choked. If it does, you have other problems, but in any event, it will not make power. More that one way to skin a cat, if your into cat skinning, or, start an engine.
