You need to get rid of the black pump cam and install a wide brown/red one. That black cam is the smallest pump cam there is and it is made for a 30cc pump and not the 50cc pump setup that SHOULD be on that 4412. That is your stumble.
Either a .028 or .031 squirter is fine, but you're not feeding it enough pump shot when the throttle his opened.

Hope that helps and let me know if you need the cam that works for that.
