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 f uels 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\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBarrel Quantity:\u003c\/strong\u003e 4 Barrel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Height:\u003c\/strong\u003e 3.25 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBooster Type:\u003c\/strong\u003e annular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter:\u003c\/strong\u003e Primary Bore 1.75; Secondary Bore 1.75 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChoke Type:\u003c\/strong\u003e Manual\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e New\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEGR Port:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Satin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Shape:\u003c\/strong\u003e Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGasket Or Seal Included:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMain Venturi Diameter:\u003c\/strong\u003e 1.525 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Flow Rating:\u003c\/strong\u003e 800\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetering Rod Size:\u003c\/strong\u003e .065 x .052 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Jet Diameter:\u003c\/strong\u003e 0.104 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Jet Diameter:\u003c\/strong\u003e 0.104 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e AVS2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Force:\u003c\/strong\u003e 5\" Hg (Orange)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":44849439342727,"sku":"EDE1912","price":794.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/4008\/1543\/files\/001912_v1.jpg?v=1788268405","url":"https:\/\/checkout.northernperformance.ca\/products\/avs2-800-cfm-1912-carburetor-manual-choke-for-high-horsepower-engine","provider":"Northern Performance","version":"1.0","type":"link"}
