'Adjusted' lamda tower screw...car won't start.

[socaleuro]

I will make this very brief...

I messed with the Lambda tower adjustment (trying to lean out mixture) and now the car won't start. I went to the max counterclockwise and even clockwise (I think it maxed CW). Messed with it some more and to no success. Then pulled spark plugs to check for flooding, rich smell was present, but then again the car has always ran rich. At this point I am going to let the car sit for several hours in case it is flooded.

Now...I am pretty much screwed since the car must be running in order to set the lambda tower adjustment (found a post on here about that) or, is it absolutely going to the indy?

Thanks in advance everybody!

Edit: Car is a '89 300E
