wOW, nice job! What did you use to adhear it to the carb so you don't loose it?
I Dremeled out the inside a bit at a time until it fit snugly down to 1/8" left to be fully seated. After polishing it, I tapped it into place... so friction is holding it there. I'd be a bit skeptic if this was my first time installing this, but I installed a stack with this same method on a GMS .32 and it's held well after 20 or so flights(not wandered a bit) and the stack tube on that .32 is not as snug.
OK, dumb question alert. What do you mean by "stand off fuel"? The stack looks fantastic though.
Thanks for the kind words. ianwynne explained it well - here is another reference regarding this:

Only dumb question is the one left unasked.
