The Weber DCOE dual-throat sidedraft is considered by many to be the definition of a performance carburetor. The range of venturi (choke) sizes and the ease of changing jets make it the carburetor of choice for many performance upgrades. The 40DCOE size can be tuned to work with a wide range of engines, from 1500cc to 2000cc. Multiple carburetors can be used to feed engines up to 3 liters (150-300cc cylinder volume per throat). Sold individually.

These are genuine Weber (not clones, copies, or licensed work-alikes), brand-new (not rebuilt, reman, or new-old stock) carburetors!
