Re: [T3] Carbs popping

<x-flowed>DougG=> It's only under acceleration, and it only occurs
=> when the engine is under load.

Might be good to look closely at this and verify. Postignition is 
unburned fuel hitting the hot exhaust, and you'll most often hear it 
when the motor is lean and winding down, between gears or on engine 
braking, and it's normal with an exhaust leak, which (in theory) 
provides the oxygen. Popping at WOT, on the other hand, might indicate 
overfueling or some inefficiency.

=> do you guys get 85 octane gas in Northern Arizona?

I don't think so. We normally see 92-90-87 pumps, iirc.
