OK, here's somethin, just found that my head was stripped, where the glow plug screws in.  I'm guessing that would explain why I've been going thru plugs like water in a carwash.  changed the head. Also had 1/2 a muffler blow off on me.  Combine that with what Lnewqban said, I did notice I had to run her a little rich, otherwise she'd sag on takeoff. Tomorrow gonna see if the new head/plug, and pipe will get rid of the vibe and leave a little less fuel on the feathers.  Any opinion on this anyone?
