WOW - you folks are informative and fun .....
@
campy - thanks for the diagram idfentifying the part.
@
mav1178 - thanks for the link with the information.
@
dsrttigr - so that's where they keep the cricket feed (I fixed them up, by dusting some DDT into the intake).
@
TRD-X - now, I didn't fall off the pumpkin wagon here in Puyallup .... I do know that the flux capacitor is part of the electrical system....cause the black box didn't shock me.

@
djleepanda - are you from the south .... ??
Well, thanks all .......... :happy0180:
This seems to explain it pretty well:
From the reference:
"The Resonator
Adding an expansion chamber to the intake tube forces air coming back out of the engine to slow down to fill the cavity, thus expending a great deal[IMG]file:///C:/Users/Roger/AppData/Local/Temp/msohtmlclip1/01/clip_image002.png[/IMG] of its energy and slowing the pressure wave reversion. This slowdown allows fresh air to flow toward the engine without fighting pressure reversion waves the entire way, thus aiding in cylinder filling. Since these pressure waves are essentially sound, giving them a place to expend their energy before exiting the air filter box ends up dampening the intake noise and quieting the engine. Thus, the resonator helps to make the engine paradoxically quieter and more powerful."
Thanks again.......

PS - no one mentioned it might be a muffler bearing .... ??
