Thanks Spiral ... I'm not trying to come off as condescending, or anything, but I'm almost certain that I rebuilt the carbs correctly. I know them inside and out by now and those carbs are put together correctly. My main concern is that the cylinders were completely flooded with gasoline, right up until the point where it was spilling out of the intake manifolds. I suspect this is the root of my problem. I drained all of the gasoline when I changed the oil, however, there's still probably a little bit left. I suspect the issue is spark and ignition, not fuel flow. The spark plugs were shot (and iridium) ... when I cleaned them off, maybe I fouled them? I have new ones coming in this afternoon. Any more advice on spark? I trickle charged the battery last night just in case I had a weak output.
