Fuel/Air Mixture adjustment 280E 1985

Hey guys So it is now stalling and won't start. Currently I believe the engine got flooded so I am letting it sit. I made a huge mistake and got the adjustment on the fuel/air to a perfect setting and thought I could make it better by making it a little leaner and now am at the point where I do not know if it is too rich or too lean. I need help with what I should do next??? My plan is to wait a bit Check spark plugs make sure they are dried out. Do half circle turns toward richer until I can get it idling again. Once I get it idling very delicately adjust to a nice no shaky idle. I only am worried because I don't know exactly if right now it is too lean or too rich and if my order of operation is correct. Thanks in advance.

find the fuel pump relay on drivers side of car near firewall.jump across pins 87 & 30 which will make fuel pump run all the time even with key off.now push down on plate[beside fuel distributor] and see how far before injectors start to sing.[if they are already singing you are too rich]now adjust the 3mm until the singing just stops.this will start car and give you a basis from which to start.

BOOM baby got it running so much better now. I am going to change the oil because the oil has fuel in it right now due to the flood but it runs great, thanks for the advice.
