X380-12K EC Intimidator Model 40-49 Briggs Intek V-Twin (2 Kits required)

1.125 Throttle bore 1.000 Venturi.

This is the only 1.125” (28.575mm) Carburetor built for OHV V-Twin Engines. Where the others fall short are in their initial design and intent for other engine applications. While all things are possible, the X380 is a far superior carburetor from start to finish. Our Intimidator Carburetors replace our 3+3 Twilight Zone Custom built Tillotson carburetor($600-1000+) with a blank body ready for any fuel circuit and modifications to fit any type engine. These carburetors are built with custom plate stacks, billet needles, and our EC signature 3 piece throttle shaft.


The X380-12K is designed for the Model 40-49 Briggs Intek V-Twin Kit(2 Kits required)
