rmillburn,
as long as you broached the subject, I want to rave a bit. It would be great if the fellows that have had problems, posted HELP questions, etc, could do a follow up if they solve their problem, and let the rest of us know what the outcome was.
We have all seen the "it just quit" or the "why are their flames coming out of my tailpipe?" or "it only runs when it rains" threads. Sometimes we reply with our best shot, hoping to help the guy out. What we need is feedback after the problem is resolved so we can say, " hey, I was right, I told him to check the muffler bearings, and sure enough, that's what it was!" or, " boy, was I all wet on that theory". That way we can all learn the solutions to the problems we see posted here all the time. I hope this makes sense...I have a tough time forming a concise thought!

Stuart.
