Hey guys, got a question. I ran into an issue with my B5 yesterday at the races. First I wanna explain what happened at a previous race, because I wonder I this had something to do with it.

I was at a race, and I was fighting high temps after the heats all day, once I came in at 280, and during the main, I was experiencing really high idles, and temped the engine at 310 after the main. Never had any lean bog issues or anything, and actually won the race. I know that this is an unusually high operating temp, and hope I haven't hurt the engine.

Well, after that race I came home and immediately richened both high and low needles about 9 hours each. And when I showed up yesterday at the race and began tuning, the issue I was having was when I was slowly increasing my throttle while race tuning, the engine would have a slight stutter when the carb transitioned from the low speed needle to the high speed. Like it would for a split second, stutter right when it was transitioning. I seemed to have fixed it after a little more tuning, but have never encountered this and was just wondering the cause. Was it due to an overly rich bottom, or top? No ideas.
