I'm not sure where you are, but I never use a choke. I do like that Barry Grant actually improved his choke over the junk Holley choke, but really, it isn't needed.
The choke, even if set as best as you can get they are hard on rings.
If your carb is even close, it will start better without the choke. It may take 1 minute to warm up a bit before you drop it into gear and move it, but that's about it.
