thanks for the up date...

so in the end can we safely 'guess' that it was a partially plugged fuel passage that was the culprit causing the 'original' lack of power complaint and every thing else that got fixed was really just required normal maintenance we can all expect to encounter sooner or later?
Truth is I think these types of issues are half the fun (if you can call it that) of owning one of these rigs. No, "where do I plug the computer in?" here.... just good ol scientific method at work coming up with theories and testing them for validity.
