Then set your initial timing to achieve the idle rpm you want. Larger cams will need more initial.
Then you set your idle mixture screws in drive simply because that's where you need the right mix, in drive ready to drive the car, with a load on the engine from the torque converter.
Then set your idle mixture screws for best/highest vacuum.
All of this has less to do with exhaust smell and more with optimizing the AFR at idle and this is how you do that short of an AFR gauge.You may very well have the right tune on your carb/distributor but this is how you do it from square 1.

I knew most but not all of this. Great explanation and step-by-step. I’ll post back after I receive and install the Moroso kit. Thanks!
