No popping on decel and runs like a champ above 50. I know it has to do with throttle, is that in my needle adjustment.
First thing I'd do is remove carb and clean thoroughly with aerosol carb cleaner (spray in all holes and jets and allow to drip off so dirt is carried away as you spray. Once that has been eliminated I would check float height and only then look at jetting.
Hope that helps
