Hsn is at 4 turns out and lsn is flush with inner ring per traxxas. after 2-3 minute of running temp is 320. then its running rich because it load up and starts to cut off on after i let off the throttle and idle screw is set. Ten years of on road and I have not seen a .12 motor act like this (novarossi, o.s., RB, etc.) ny suggestions
