Could I suggest you post a series of pictures of the process of replacing the gasket? A close up or two of the piston without the gasket on it would be great as part of that. I am sure others would benefit from your experience. For myself I occasionally try and make a DIY fire piston and I am finding it hard to get the whipping to lay flat where the cord crosses over the underlying cord.
