Jerry, Saw the comments about the muffler, did it have the long
rectangular exit? I still have trouble about the VAM pipe, since they
ran it without a tailpipe. (wihch was totally necessarry to the
design) I know they couldn't fit it on Tracy's test stand, but I
wondered if your pipe suffered the same fate? Thanks for the offer of
the updates of the other list if needed. I really don't know what the
problem is. Flyrotary gets bounces too sometimes. On your machining
problem, you can order a custom sized reamer pretty easy from a
machine shop supply. Takes about a week and they aren't even all that
expensive.
