Does anybody know the setting for the screwjets on a Mercury sportjet 120(1998) with twin carbs.<br />some people say there air jets and should be 2.5 turns others say there fuel jets and should be 1.5 turns. Neither work for me, 1st one runs rich, 2nd one tick over is high. Also is there a downloadable manual anywhere?

Manuals for sportjets are gone from biggerhammer site-don't know of another place. I have the 95-97 complete manual, pm your email addy if you want that.

Those are only idle mixture screws and only work when the carbs on on dead idle. You probably need to rebuild those carbs if one is running rich.
