Besides what glernnster says,the fact that it likes the choke could be due to a lean condition. In cold weather it's common to have the the carb lean out because the air density is greater.

As the throttle opens the fuel comes from a transistion port on the downstream side of the throttle plate.)
Another possibility is that you have an air leak around the metering section of the carb(Throttle shaft seals, connect flange between carb and intake manifold, or manifold to head connection or a cracked/rust hole in the intake manifold).
