Would anyone know what the factory setting is for the one hi-mixture adj. screw is in number of turns out is? As when I got this HC150 it was running vary rich, black plug, oil dripping out of the muffler etc. I turned the Hi speed adj screw in a few turns and runs accelerates much better and can idle forever if I let it.... but with non-eth 93octane fuel and Amsoil Saber mixed to 80:1 it really screams at wide open throttle but still smokes? so I would like to know if possible the factory setting of the Hi speed screw located by the primmer bulb. As i would like to tune this right and correct.
