Dan on the carb issues yes I think we have that solved. Took vette to Dub at Corvette Etc in Charlotte, a great vette machanic. After replacing the S hose no problems since. Dub also adjusted the carb and ECM setting so so far no probelm and MPG improved slightly, from 11 MPG to 13 MPG around town. Right now it ride and enjoy, well as long as the weather around here is good, heading out to a christmas parade in a bit with other vettes meeting up to have some fun.
On the buffing the car I may take it to a good detail shop we have locally and let them do it. They have turned out great looking cars but will talk with them about the clay bar method.
