a.k.a. idle mixture adjusting screws. Not the idle speed knob.

Popping on shut throttles is caused by the pilot circuit en-richening screws
being set too lean. which they HAVE to be for emissions.[...]
The carbs are otherwise jetted OK up to 6000 rpm when they go rich. > You need to adjust your pilot screws out ...there's notes on this in the
files section. That stops the popping.

Pop quiz ('cause I don't know the answer):
Engine pinging on acceleration or uphill, and exhaust popping (like a
baby backfire) on downshift are symptoms of what, specifically?
Mixture? Carb asynch? Something else?
