My experience: All of the remaining 2-stroke powered equipment being sold today are being tuned 'lean' from the factory to reduce emissions and smoke. That little carb has plastic 'limiters' on the mixture adjusting screws / low and high speed fuel circuits. Typically only allowing @1/2 turn either way.

They are installed by the factory to prevent 'Joe Consumer' from 'adjusting' the mixture out of range to the point of not running.

You are running lean on both. You'll need to first carefully turn counter-clockwise the low speed fuel mixture screw to the limit / limiter range. See if that cures the problem, because that is where you need it somewhat 'fat' when idling - so when you hit the throttle, the cylinder is loaded properly with fuel to accelerate as there is no accelerator pump shot.

If the mixture does not 'fatten' up enough - you can force it gently further by continued turning further which will break the limiter cap to get into the range you need.

Those screws should be clearly marked 'Lo' and 'Hi" - also do not confuse those with the idle speed screw which is a separate adjustment that does not have a limiter cap.

Any happy 2-stroke should emit a nice rolling, 'gurgling' sound at idle. Then instantly RPM when the throttle is hit WO. When held WOT and no load - there should also be a slight 'gurgling' that cleans up when a load is placed. If not, you'll need to adjust the 'Hi' speed mixture screw in the same way.
