My engine always ran good, though the early muffler design sucked. There was nothing to keep it from collapsing causing the mounting screws to loosen. Second version of the muffler is what I feel caused the loss of interest on Todd's part, as it seemed that those were released about the same time Todd lost interest in the project. Making and shipping all those mufflers had to be expensive, putting the project in the red for sure.

Today, I view the engine as a quality made mistake. I feel for those stuck with them. If I still had one I would run it until it broke and move on. I doubt it will ever become a collector's item, but you never know with such things.
