When I first hit the track, the engine was very rich at the bottom. It was so slow, it can barely shift 2nd even at 200F! I lean the bottom about 1.5 turns and the engine ran a lot quicker but still slower than the stock Mega. Now the bottom end is set just below where the engine is idling high. The temp is about 215F and it's still blowing out a lot of smoke. What temp should I keep it in?
