HL-304WX-5K Dominator Plus Alky Tillotson Carburetor Kit for Big Valve GX200/Clone

The EC Dominator is machined and blueprinted for Open or Big Valve Honda GX200 and other Small Block Clone, Predator, or Tillotson Engines.

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 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 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 are 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.
