I have a JoeBlow Sport (not a Sport II or Sport III)

It head defaults to schrader style. There was an adaptor in the box which I thought was a presta adaptor.

presta adaptor?

I tried sticking that adaptor in the pump small side (screw side) toward the pump, other on the tire presta value. No matter what I tried I could not get the tire to take air (yes, I unscrewed the lock on the presta valve)

I looked for some videos and the manual but I can find nothing on the JoeBlow Sport. Only the Sport II and Sport III which have a different head.

I found this video about some other head and how to change it. It involved opening the head and flipping parts. So I opened the head on my JoeBlow Sport but I can't see any way the parts fit differently.

JoeBlow Sport head parts

If I flip the second part from the right end, it's black and rubber, it looks like I'd expect for a presta valve but it's impossible to close the head back up with it upside down. In fact I can't see any point in being able to open this head, flipping any piece whatsoever makes it impossible to close.

Can someone explain what I'm supposed to do here?

I figured it out.

I needed to screw the adaptor on the presta tire valve, then attach the pump head. I was instead putting the adaptor in the head and then pushing it on the value but it needs to be screwed on first.

I feel dumb but at least my tires are now inflated

    That's the ticket. Chances are, if you've had a query about bikes, someone else will google the same query in the future. Feel free to mark this as the accepted answer (green tick) because it solved the problem
