I thought I would post the end result on this so maybe it might help someone else along the line later on- It turned out to be the gearbox, sent it out to Jim Scott at Aircore Aviation in Arlington, (great guy and highly recommended) got it back in record time(would have been faster but parts were back ordered) bolted it back up, retorqued everything, safety wired, fired up and she runs smooooth. no puking carb, no weird noises. And my plane only has 145 hours on it- so go figure.
