hxman,
I've helped a number of NexSTAR owners, this year during training nights, and at least half of them had the colors mixed up.
Assuming you haven't been airborne, yet, you'll probably have difficulty getting the engine to run. Because, the carb is connected to the vent tube in the tank. Remove the tank and verify which color tubing is connected where, in the stopper.

Let us know.
