Help! New Carburetor????!

Got it running finally. On test run the carb under load has a major vacume jet engine sound at mid range, med load, going to heavy load add high pitched whistle to the jet noise! Still no kick down. I guess I would have to adjust rod to tranny down and kick down sliding rod back a litle? What the heck is that noise it's making?????????
Anyone know what is going on with it? Please advise and Thank You Again!
Runs stonger than before and once it plains out at 70 everything quiets down except exhaust rumble.
