Is it even possible to make these things start smoothly?

Yes. It requires slightly heavier flyweights and/or a lighter control spring in the primary. Together the tip-in will be at a lower RPM and a slower engagement. The trick is..you can not have it start to engage any lower then 300 RPMs above normal idle otherwise you run the risk of not disengagement at idle. I normally suggest starting with flyweights around 5-7 grams heavier then stock but many are going with much more to my surprise. Springs will depend on what's in there now on those without wet clutches. But you want one with a lighter starting pressure then stock and if you like how it shifts after it gets going, stick with one with about the same second number. Cake.

That's too much to digest for my bold brain.  I've had the drive cover off and it's not much different of a setup than what is in go karts.  Maybe a video or play by play would make sense to me.

Lol..well once you have in your head how they work, it will seem easy. This video had helped some start down that path:
