Flipping won't matter, I've reversed them, no difference. Skipping to another hole will matter. The tutotial above is a good one. I used the 16" rim directions from hondachopper.com too.
I do innies on one side, turn it to draw in the nipples. Flip it over, do the innies from the other side, the opposite direction. Watch to see where the rim holes are aimed and look for the wear marks on the hub. If you weren't half a world away, I'd say bring em over.
