    Oil injection

    I have a 1991 mercury black max 150 #0D038864. I recently deleted the oil injection and now its running rich. Do I need to adjust something on the carbs? all the electronics are in good shape brand new spark plugs and Gap correctly. Also I can't shut that alarm off for the oil tank just a constant beebing any suggestions? Thanks

    Did you remove the oil pump from the motor and the oil drive shaft?

    Yeah I sure did oil tank is gone and I bought one of those quick silver oil pump delete stick that goes into the block.I made sure to use brand new o ring before installing. Know I notice on that stick one side is flat while the other round I just twisted till it fell in place. If I can't get that alarm to shut off I plan on reinstalling the oil tank with float and hook wires back up just where I don't have to hear that.

    Remove oil module, remove motion sensor, just above oil pump. throw them away. premix oil between 40-1, or 50-1. If it runs rich it may be idle air valve on stbd. head. that has hose running to carb. body. it allows more air to idle circuit after motor warms up. If plugged will always run rich. Also unhook advance or idle module, on this motor it starts retarding timing advance after about 5,000 rpm. It also has a cutout in exh. port in block that will limit power output.

    Ok thanks billybob. Just ran all the wires down and disconnected them, alarm is gone I mean everything haha no been at the turn of the key But it runs fine. I was wondering what that air valve was . when I got the motor it was just blowing free I thought that cant be normal so I plugged it up ill have to find where this goes and hook it up. Ill let y'all know thanks for all the tips. I got this thing on the back of a 17ft king Fisher and man that thing rolls I thought I was doing something with that johnson
