I have a Super Tigre 45 that keeps blowing the gasket out between the muffler and the head. After the gasket blows the screws holding the muffler vibrate out and the muffler falls off. I'm running the motor on Sig 10 %nitro fuel. Any idea how to stop the gasket from blowing out or what maybe causing the gasket to blow?

I love the smell of nitro in the morning
