pricey and hard to find

my 1992 xv5352yl  started coughing and spluttering dirt in the carbs I suspected some job to get them of even worse ive heard putting them back, anyhow I stripped them down cleaned everthing went to set the mixture screws two of them totally chewed to bits could not move them  so ithought I will look at ebay etc see if I can pick up a fair price set of carbs as rare as hens teeth ,the only decent pair I saw was £249 but they had been rebuilt but the buyer said the front cylinder mixture screw was seized and could not be moved but he said its at factory setting and he said t they ran ok on the bike that he was breaking  when I had my old 38 year old cm 400 I could get a set of carbs for under 40 quid canny believe its that kind of money for a 25 year old bike anybody want to swap a virago for a decent Honda cb400 superdream lol
