idle issues with new A500 behind a fresh 318

Guy on the phone from Edelbrock seemed pretty straightforward about replacing the carb this morning, but I haven't seen the promised return authorization in the e-mail yet. I'll let you know if Eddy stands behind their stuff. I have 3 Eddy Performers (AFB) and another AVS2 on other cars and they have run great right out of the box, some of them for close to 20 years...
