Okay. I'll try that, although I was running the A3 when it started to act funky. I replaced it with a new one and it seemed to help. I guess I'll see tomorow. I've had enough messing with it for today. How exactly do I replace this "O" ring that you guys keep telling me about? Where is it? If I'm thinking of the right one, then you guys are talking about the one on the base of the carb, right?
