Also, i've got the 42 in. I still use the choke though when it's this cold out.

From what everybody else was saying i thought the 42 would fix the cold start blues. It helps the quad idle a little sooner after warmup, but i still use the choke even with the 42 pilot, otherwise i have to crank it over too much.
Personally I would want to have to use the chocke on cold start up. If you dont need the choke when its ice cold, then when it warms up you are running too rich, at least from idle to 1/4 throttle. rich is fine and safe, but you start losing power the richer it runs.
