I runs rougher either way I go on the screw. The manual says ideal is 1 1/2 turns out. I need it to be 3/4-1 turn to sound correct. If I turn it out it will run rougher. So in that case the mixture screw is working. This is a really bad run on. It will knock and kick for 15-20 seconds and then light up and run for 15-20 seconds or more.
