| it sounds like it may be starving for fuel at high rpm
go over the fuel lines fuel filter & be sure the vent hole in the cap is clear to breathe
if that dose not help you may need to adjust the H mix screw out 1/8th of a turn then test
initial settings for the H screw is all the way in then 2.5 turns out, once its set you fine tune 1/8th of a turn at a time in or out
in for less fuel out for more
dont touch the L needle low to mid range is ok as the H needle will determine high speed mixture
