1991 mercury 150 black max. Deleted my oil injection and now its running a little rich. All my electronics working good and new spark plugs.do I need to adjust the carbs? Also a constant beeping keeps going off cause I unplugged the wires for the float. Any way to disable that? Thanks

what ratio ya using?... they will tend ta "smoke" a little more at idle if that's what ya mean "rich".. nothing you can do about it except go to a synthetic oil.. will help a little.. ya need to remove tha oiler module ta stop tha beepin'... your self check beeps will go away also.......

I'm running 50:1 oil mixture. I removed the oil tank and pump used the quick silver packed for pump replacement.is there any other wires to disconnect besides the two from the oil tank?

follow tha wires from tha motor tank back to tha module.. its a black box about 2 1/2 inches by 3 1/2 inches with several other wires going different places..should be purple, green, 1 possibly 2 lt blue/white, tan/blue, white, black all comin' outta tha "module".. disconnect 'em all (jus tha ones comin' outta tha module) and ditch tha module.

ratio is fine with a "good" oil..
