Lean condition under light acceleration

The metering rods are adjustable.I think the cruise step is tapered;just crank them up or down as may be required. You may need a slightly richer cruise-step, or a slightly higher wet fuel level. I noticed years ago, mine ran better with a lil higher than stock spec.

Yeah, I think richening the cruise up will be a good place to start. From some past fiddling, I remember a failed attempt at using Edelbrock metering rods that yielded awesome part throttle power but choked at WOT. It would have been delivering more fuel than my current setup at part throttle.
