Well, after working on my carbs, my low speed is rough. All plugs after a high-speed wash is great, but after low speed running (1400-2400 rpm) for a minute, the middle plug is black. I sure thought i opened the idle screw 1/2 but those springs are really strong. I'll check again tonight after removing the spark arrestor, but I'm afraid of mashing it down too tight.
Any other ideas?
