Why are you complicating this Gordy???...He already said what his plug looked like using the chart...I circled it in red so you can see it...Must be using that dumb phone again rather than a real computer so you can't see what he is talking about...lol.Is it grey or brown? If it's grey then it's running lean. If it's running lean you're experiencing a 'lean bog' which if it's just a little lean it can almost seem like it's fourstroking. My bt80 did that and it seemed like it was fourstroking, but it read lean.
Gordy, if ya keep using a stupid cell phone to access the forums your gonna wind up like this guy...lol...lol...lol.
