Poulan pp19a42 spudders

[memineinc42]

Hello, any help is very appreciated. Spudders under load when the blades are engaged, then I can adjust the throttle lower and its stops misfiring. The plug is covered with black carbon after a short time. The carburetor has a couple wires that connect to the bottom of the bowl and I think it has and air fuel mixture screw on the top edge on the side. Someone told me there was a know issue with these carbs but couldn't elaborate.
Thanks!

If your hood looks the same as the one in my avatar I would venture to guess it's over heating. Mine did that when it was brand new. Ran fine with the hood off.

Thank you Bob E for the comment. I think it might be the carburetor out of adjustment. Does anyone know if the carburetor has an air fuel mixture screw an the easiest way to adjust it. Thanks again.
