The HL-304WX bodies are designed as the OHV versions of the HL-348 Carburetors. Built to be the new super stock or limited built carburetor for the OHV kart racing markets.
Tillotson Carburetor Numbers ending with G or A does not indicate whether its a Gas or Alky Carburetor. This is a misconception made by the fact the HL-334WXG, HL-304WXG are gas carburetors and the HL-334WXA, HL-304WXA are Methanol(Alky) Carburetors. The numbers are usually the body core and the letters are usually the blueprint or fuel circuit design or revision made on that body. Check your listing before ordering.
The HL-304WXA’s fuel circuitry is designed as a mild methanol(alky) blueprint. This makes run out of the box on virtually any OHV engine around 200cc in displacement including the Briggs Animal, GX200 Honda and the many Clones and Predators. It has enough room for improvement based on engine class rules and modifications without needing to lean the circuit.
Run only on pure methanol. DO NOT USE ANY TOP LUBE! Do not confuse Methanol with Ethanol- it will not run on Ethanol or ethanol blend fuels, Period!
Engines with camshaft bigger than 275, more displacement or bigger than stock valves will have more gains if the HL-304WXA is blueprinted. You may find our Dominator 304 better suited for your application.
