after taking my carb off and on several times in the very beginning I damaged that same gasket. How is anyones guess. Maybe it just wiggles when you connect the carb to the pipe. I know yoiu must have checked the nuts on that intake. I not I would tighten those before I replaced the gasket. I cut that gasket from a cereal box. That was several months ago and it works just fine. On these bikes for all intents and purpose I think they are.
