Intimidator X series

Intimidator Billet XHR for billet big briggs 305


XHR-3K EC Intimidator OHV Billet Briggs 305/342 Kit

This 1.355” (34.417mm) Carburetor built for OHV Open Engines. Where the others fall short are in their initial design and intent for other engine applications (most commonly 2-Stroke). While all things are possible, the XHR is a far superior carburetor from start to finish. Our Intimidator Carburetors replaces our 3+3 Twlight 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. Unlike Tillotson HR carburetors that have a velocity ring (bull’s eye) the Intimidator does not. This increases flow significantly without disrupting the design of the carburetor.


The XHR-3K is designed for the OHV Billet Briggs 305/342 Kit
