I agree with rocco on this one. I know "New York cold" and "California cold" are pretty different, don't get me wrong. But I have plenty of below freezing starts on the Eddy air gap on my my 340, never had any issues with it. It fires immediately on the first crank, dies before the electric choke kicks in, and runs 99.9% of the time right off the 2nd crank. That's with a street avenger carb with an electric choke.
But yeah, I'm talking less than 32*F and usually more than about 28*F, it usually isn't colder than that here when I'm trying to go to work. So, if you're talking less than 28*F, my comments may not apply.
