I know what is wrong....
You have a GT6+.....the carbs have that little plastic cover on the sides of
them???
Well, remove this, and you will find a little bimettalic strip which when
should plug the hole it covers. It is some sort of crappy attempt at
emmisions. Just screw the bimetallic strip down HARD so the hole is
permanently blocked....this is where the air is leaking in to make
it idle high!

P.S. A TR mechanic said he sees this all the time on these carbs
