Annular Flow Boosters deliver near EFI-like drivability that you can feel as soon as you step on the gas. Fuel distribution is refined by eight equally spaced orifices in the booster rings that replace down-leg boosters which simply dump raw fuel into the venturi. Flat spots are completely eliminated, and throttle response in the low- to mid-RPM range is improved tremendously without sacrificing that top-end power that Edelbrock is known for. The AVS2 is unaffected by engine backfires since there are no power valves to blow out. For fast and simple part-throttle tuning, metering rods and springs can be changed in seconds without carburetor removal or fuel draining. AVS2 carbs have the unique ability to \"hold a tune\" when compared to other carburetors. Your tuning and adjustments stay unchanged, so performance remains consistent. Updated primary and secondary booster clusters in the AVS2 offer the most accurate and up-to-date calibration available for today's fuels and octane levels. Additionally, the unique Qwik-Tune Secondary Air Valve allows for limitless calibration of the secondary circuit. Adjustments can be with simple hand tools in seconds to suit your application. The AVS2 features a two-piece ease-of-tuning design that lets you make float level adjustments or replace internal components without draining the fuel from the carburetor or removing it from the engine. The AVS2 800 CFM #1912 comes with a manual (#1912) or electric (#1913) choke in satin or chrome-like EnduraShine finish. All AVS2 Series carburetors, like Edelbrock's popular Performer Series and Thunder Series AVS, are designed, manufactured, assembled and calibrated by Edelbrock in the USA.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrings Superior Fuel Atomization\u003c\/li\u003e\n\u003cli\u003eAnnular Flow Primary Boosters\u003c\/li\u003e\n\u003cli\u003eFuel Distribution\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: \u003cspan\u003ePrimary Bore 1.75; Secondary Bore 1.75\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: \u003cspan\u003eAVS2\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eChoke Type\u003c\/strong\u003e: \u003cspan\u003eManual\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eMain Venturi Diameter\u003c\/strong\u003e: \u003cspan\u003e1.525\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eMetering Rod Size\u003c\/strong\u003e: \u003cspan\u003e.065 x .052\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eGasket Or Seal Included\u003c\/strong\u003e: \u003cspan\u003eYes\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eBody Height\u003c\/strong\u003e: \u003cspan\u003e3.25\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eFlange Shape\u003c\/strong\u003e: \u003cspan\u003eSquare\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003ePrimary Jet Diameter\u003c\/strong\u003e: \u003cspan\u003e0.104\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eCondition\u003c\/strong\u003e: \u003cspan\u003eNew\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: \u003cspan\u003eAluminum\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eSpring Force\u003c\/strong\u003e: \u003cspan\u003e5\" Hg (Orange)\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eBooster Type\u003c\/strong\u003e: \u003cspan\u003eannular\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eSecondary Jet Diameter\u003c\/strong\u003e: \u003cspan\u003e0.104\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eRGL\u003c\/strong\u003e: \u003cspan\u003eWARNING: This product can expose you to Lead, which is known to the State of California to cause cancer or birth defects or other reproductive harm.
