tryin to break in new engine, ruff idle

I would bump the gap up to .045. You can always coose it up incrementally if necessary. All the new electronic cars call for a wider gap. Allows the coil to build more voltage to jump the air gap. When you choke the motor you are actually enrichening the fuel mix. How have the plugs been looking?
I believe that in one of your earlier replies you had checked for leaks. Did you spray around the carb base and the intake with WD-40 or brake cleaner or even water ?
