Help me out here I think I'm experiencing what in this article is called lean bog. I notice it after about 5-6 minutes of running. My engine is the alpha lutz worlds edition I was coming off the track about 240. I've richened up the hsn as per the article says, coming off about 210 and it still lean bogs when getting low on fuel. I don't wanna richen anymore I'll start losing performance and temps will lower I'd like to be able to run it at 240 for racing. What can I do to rectify this issues is it possibly something else causing the issue??
