You do not need a flywheel and billet rod until you remove the governor. If you decide to remove the governor then do the flywheel and rod at the same time.
You can go with a slide carb like the VM22 but you should learn as much as possible before getting one. They have been frustrating to a...
First. Shouldn't you be using the recommended valve springs with the cam? Should be at least 36 lb.
Not a good idea to use stock rockers and stock spring retainers on a build like that.
I don't think you would want to use ratio rockers with that cam. May end up with clearance problems. Use...
Not mine. Thought some of you may want to see this.

Quality bearings such as?
Last bearings I used were to do both of my TAV plates. One got Timken and the other PGN. These days I'm no more confident in the Timken's than the PGN's. I did use the Timkens in the bike that has more power and ride time.

Look at the reviews. There may be helpful information.
Another comment about this.... I'm not serious about slide carbs. That's why I...
With the 6203 bearing it's stepping down from 17 to 16mm for the sprockets.
That was the problem from day one of the tall tire bike jackshafts. You couldn't find 16mm bore sprockets for an easy gearing change. Otherwise there would have been a ton of 14-16 tooth sprockets sold to replace the...
The key that is left is too short. At one point it broke in half. They had one 5mm key that covered both sprockets, at least 30mm long.
I'd bet that Coleman sold a lot of those jackshafts. In your case the jackshaft (not the assembly) and a new 5mm key would get you going. The sprockets may be...
The OP may have watched several and think we're full of it for being concerned about the governor shaft that's still in the block. He may have watched Black66 running 5K plus RPM in one of his videos with the shaft still there.
The speed calc (the math) isn't always accurate because engine power and load are not in the equation.
5:1 gearing is already not very good for performance against a 19 inch tire. 4:1 and a taller tire would be horrible and you would need a lot more road to get up to speed.
