16hp vanguard not idling well

So I finally got my exhaust welded up and now I can't get the engine to idle well. It starts but won't idle.

I have the Rev kit in it and the valves adjusted. Governor is bypassed and throttle I straight to the carb.

I have the Equus 8068 and I think I have it set up right. If I do it idles at 2000 and then when it drops below 1500 it dies.

Took apart the Carb to clean.

Got rid of the fuel filter in line.

Plugs look good.

Fuel pump is getting pulse off of valve cover.

Any other ideas?

Also, what is this black screw for. I think it's a idle screw but it doesn't seem to do anything.
