Wigwam help!

So I decided to learn a cabin tut. Tricks not so difficult but I’m having trouble with the restart part where yuuki catches the yoyo, and gets it spinning again. Does he just quickly roll it to spin or a kind of snap? Any help would be appreciated

Looks like he does some sort of palm snap thing, then finishes it with an “Engineer’s Windup.”
The one where you double up the string and roll it out.

I’m sure you’ve seen it before but if not it’s on this page:

Just look for Engineer’s Windup.

As for the palm snap thing, sorry I’ve got nuthin.
