RE: starting with the choke on?
As I said on cold mornings that normal procedure will take many flips and re-chokes....if you like your low end lean like I do. I found that the partial choke gets it running right away on even the coldest winter days. As was mentioned, many ways to skin a cat. But you better have that low needle pretty fat if you want to start on a cold spring, fall, or winter day....with that choke fully open. Then you're stuck with a fat mid range once it warms up, no fun.
