A Pig Roast sounds like fun. Is that over at Scott's house? I'll log in on the local and see the thread. The gas I use is always 93 Octane, and generally Exxon, Shell, Sunoco, etc. But they always say they have ethanol in them. I don't think you can find non-RFG (reformulated gasoline) in the DC/NoVA area. The Holley 4160 is really dirt-sensitive. In fact, unless something like a Power Valve fails (and they don't really blow out much anymore), or an accelerator pump fails, there's not that much to do with them other than keep them clean. Once you get them set up right, they'll stay that way pretty much forever... until a spec of dirt gets in. If I'm at the pig roast I'll show you the air bleed cleaning. You have to be careful on a hot car though. I zip-tied my throttle wide open so I could peek down it with a flashlight when I squirted the cleaner down the air bleed. That way you can actually see it coming out down at the idle hole. Then I closed off the idle mixture screws and did it again so the pressure blows out the little air holes down the tube. Then just set the idle mixture and idle and *presto* the engine's good as new.
BTW, the idle circuit is not just for idling -- it affects your low-speed drivability quite a bit.
