just bought an '87 3.2 L motor with 46 IDA webers and headers to put in my '72 911. When the motor was installed, the car began to have a bad backfire when decelerating that wasn't present before the new motor installation. I have had 2 good mechanics in the Los Angeles area look at it, and both told me that I will always have the backfire because of the carbs. I know people have done this setup and theres don't sound like mine. This is a nice looking car that sounds like crap. WHAT DO I NEED TO DO TO GET RID OF THIS BACKFIRE?????
Thanks
