sorry, the other thread dropped off my radar...

I'd start at about a 190 middle clip 1.5 turns.

the PJ you'll have to fiddle with the screw to figure out what you need. IE if the screw is farther out then get a different jet, I forget what direction you go though..

Do some plug chops with that jetting, and go from there.
