try adjusting the low speed needle, very sensitive, small increments.also if an old carb,take it apart and clean with carb cleaner,theres a mesh filter at the bottom section,clean it,and clean the jets with carb cleaner tooHi it's got standard exhaust on it from factory, it feels fine when pulling but does take more pulls then usual to fire, if you prime the bulb with chock on it can take 5 or 6 pulls before it will fire, thanks
i remember, i once was doing some high speed runs, i got 41mph on gps ,then i moved the hsn about a mil,hardly moved it,then it gps ed at 51mph, mAssive difference withthe tinniest adjustment! can you make a video of it running, make sure the carb open fully on wot, if you don't know what i mean,let me know and ill send u a vid!
actually my km baja was very laggy at low revs,,bnut after time it dissapeared lol.im just running an engine in at thye mo,am having a few issues,but normally get sorted out, good luck.
