420 w126 flooding only on pass side
 

I over-adjusted the lean/rich adjustment screw I realize now but here is the weird part..it only floods the cylinders on the pass side only. Ive pulled the plugs nothin gon the driver but when I turn the motor over it SHOOTS out the pass side. Im a halfway good mechanic on demestic cars so Im not a total dumbass, I replaced both cams and rockers last year and drove it 10000 miles without prob. but thgis prob is baffling me....Help..THANKS:(

If nobody knows anyhting about this could someone direct me to someone who does/(on the net of course). I need to get this thing running..Peace
