Re: engine backfire when slowing down
A bit of popping when decelerating is normal and sounds great. The closed throttle plates and higher vacuum cause the mixture to go rich. Double check the color of the spark plugs or the color of any soot buildup at the ends of the tail pipes.
If it's too dark the normal running mixture could need to be leaned out a bit.
