Torque response is all in the pump. A reputable pump shop will put in the necessary parts to make it respond like a rabbit. I have a 4430 that has had this done. Starts great even when cold and has tons of power. I also have a 4630 that was always a dog and would wait for the engine to loose a couple hundred rpm before it would respond. Tightened down the aneroid and now is much better responding.
