I recently replaced the muffler on my K321A. I re-used the original clamp, but now I have a small exhaust leak where the muffler attaches to the exhaust tube. I have taken the muffler off three times attempting to stop the leak, but have not been able to completely seal it.

Is it because I have an after market muffler? Or is it normal for the K321A to have some exhuast escape before entering the muffler? it is not a "major" leak, but I can feel it when i place my hand near the clamp connection. It is also leaving some streaks of black carbon on the exhaust tube.
