From the way it acted on me, screwing it out seemed to make it more lean while screwing it in made it more rich.

Mine was running rich, but as I screwed it out, it cleaned it up. And just to get it started, I had to screw it out a little bit.

1987 Dodge Raider, 2.6L, manuel, bone stock with a whole lot of new and refurbished parts. Brought back from the dead after 12yrs.
