The EC Dominator is machined and blueprinted for Briggs & Stratton Animal(Model 12) on racing snowmobiles.
Our EC Dominators have been "dominating" the competition, setting records and winning races for decades. Our expert knowledge and years of winning history go into each hand-built Dominator Series Carburetor. Our team of EC engineers developed the only 4-cycle carburetors for Tillotson, including the "infinite radius" design to improve flow and fuel signal making it superior to other stock diaphragm carburetors.
We then prepare the Tillotson carburetor for each engine combination to maximize performance and to push the rule book for every advantage and still pass inspection.There are dozens of procedures our master carburetor technicians go through to create the dominator plus carburetor; here a few we listed:• The velocity stack is permanently attached and machine matched to the carburetor body• The carburetor body is machined and highly polished to maximize flow• The throttle shaft is polished and aligned for max flow• A hand made Trix throttle shaft screw• The fuel circuit is machined and calibrated to increase acceleration and max power.
