I'm getting ready to go fill the tank with fresh 40:1 to test rupedoggy's settings with a full tank. If I'm still having issues I'm going to put the OEM carb back on and give it a go. The OEM carb has both needles open about 1.5 turns.If you have not monkied with the OEM carb settings check them and set your new carb to the same.
You might consider re-installing your OEM carb for a test. If it's worse consider installing a kit in the OEM carb if the kit can be had at reasonable cost.
Was the new carb a $10 with free shipping China clone type??? (just curious here)
Chaina is getting better at cloning carbs but I still don't completely trust them YET.
I ordered the new carb off of Amazon, it is Chinese made. I went for the most reviews with the highest ratings. I have a carb from this manufacturer on my mower and trimmer that have been working great for over a year so I'm comfortable with them. However, that doesn't mean I couldn't have a bad one. We'll see.
