I've had this trophy 3.5 buggy by HPI for a couple weeks now. I broke it in using odonnells 20% race blend with 8% oil. Its ran great for breakin and several tanks after. Then i switched to byrons 33% with 16% oil and it ran one tank fine and picked up a bad low end bog. I figured it was the oil content so I've switched back to the odonnells race blend. I stuck a new lpr #7 medium plug in and she fired right up and as soon as it gets up to running temps around 210-230 it starts bogging at low rpm again. No matter how much i lean it it still does it and only at low end. As soon as it gets up it runs like crazy! Then after a couple of passes with it bogging at low end then picking up it stalls. I've went back to factory settings and retuned her at least 7 times and i end up back in the same spot. She will idle fine for a min or longer and as soon as i put her down and gas the throttle she shoots off like a rocket till temps get to good range and the bog comes back along with stalling. What am i missing? I'm the dang tech at my lhs and have suddenly lost my tuning ability on my new buggy. Someone help me work through this problem. You guys have never let me down yet. :\
