Tanner,
Once we back flushed the fuel line up through the tank, we got good fuel flow and had it running fairly well from idle to wide open. Then it started acting up as dirt re-entered the system. Those idle and fuel adj screws should make a noticable difference or you still have blockages somewhere.

If everything is cleaned out now, put an empty can under the carb, pull off the carb bowl plug and make sure gas is running out fast enough that you are afraid it will rapidly drain your tank. Watch it for 30 seconds or so, don't just look for the initial burst of fuel as it empties the carb bowl. If it's not running out well, go back to the sediment bowl/petcock valve, or the carb inlet screen (differentiate by checking flow at inlet to carb also). If it's got plenty of fuel, pull the adjustment screws out and run carb cleaner through those passages. If that still doesn't do it, pull the carb back off, dissasemble it to clean it all out. You can run guitar strings up through all the passages to help, but if unsure bring it to me after you have everything removed and I can set it in the dip tank overnight and then blow the passages out. If you want to check float operation, you can get a large glass or plastic(clear) bowl, just remove the carb bowl (while the carb is still on the manifold) and hold the glass bowl in place under the carb alowing you to watch the float operate and verify that the needle valve is cutting off. You will still need to visually check to make sure the float is not offset and possibly dragging on the side of the carb bowl though. I wouldn't expect it first, but another real possibility is the new plugs are already fouling just due to all the fooling around we've been doing.

I don't remember seeing any fire out the carb inlet? Is it possible that the firing order got out of whack? I remember the plug wires were all long, have you rerouted the wires to shorten them by chance? If so, verify #1 plug wire still comes off the cap at 2:00 position, and follow clockwise rotation around the cap for the firing order.
Hope that helps,
Stan(VA).
