After getting a sun tan in wee Alberta, nice place by the way,
back home to the cold, well chills to you harden lot...
Making the butterfly for a over sized TB is easy, you don't turn a true
round plate, but offsett a brass sheet at about 10-15 degrees in a
jig and them turn it so the edges seat on the bore, getttng the right
angle is a wee bit trial and error, as long as you can reset the TPS
its not so critiacal.....
