Starts with no choke or throttle engagement and idles. I hit 60 mph with it and probably has some more in it. Don't know what's in that carb but one day I am going to find out. I ordered a stand alone carb like the one you show a link to. Hopefully it has a Keihin pilot jet.

If the one you ordered is from the same store, then you should be good to go. The other two people that ordered one around the time I ordered this one bought that exact carb and it takes normal pilot jets.
This is ChondaChondaChonda's post from the older thread, he ordered the exact kit I linked, and this is some very good shots of the carb and the jets. The YOU-ALL cast into the body always gives me a giggle.

As far as the stock carb and the idle issues. I honestly think it is actually a design flaw in the pilot jet itself that causes it. Even my pumper, which uses that same style jet, has a tempermental idle sometimes. Even in the same conditions on the same day. I would almost wager it has to do with the fact that the main body of the carb that sits in the bowl leaks a little fuel or air past the outside of the pilot jet. Traditional pilots screw into that location, so the threads somewhat seal it off, but since the Hawk threads it at the very top it has to rely on the two surfaces seating against each other, and I think they just don't seal well enough. This is probably why the Mikuni is so easy to get dialed in, and why the TT250 and other bikes that use a PZ30 with more traditional pilot jets don't have the same issues as the Hawk.
If I were going to do this all from scratch, I would order that carb kit and (enjoy the free grips lol) nand the jet kit I linked from Amazon. Sure, it's $57 all said and done, but you are getting a good number of upgrades from stock for your money. Quick turn throttle with a CNC housing and thick plastic throttle tube which is quite nice I might add, the pumper carb itself, and some nice grips which are bound to be better than the stock Hawk grips... anything is better than those things.
