This is our Baby "Killer" Tillotson carburetor designed by Tillotson LTD. that Roars like a Lion and is used in Europe and South America for the Cadet Classes.
Here in the States we also use this carburetor for some of our classes like the US - 820 Classes and the Tecumseh Motorsports H-50 5 HP Class that have to have a tech size carburetor with a 19 mm (.750 inch) venturi and a 25.4 mm (1.000 inch) throttle bore. This carburetor like its Big Brothers the HL-348E, HL-355E and HL-360B is designed with a Infinite Radius from the filter adapter mounting flange to the throttle shutter. The HL-334A carburetor is an engine builders DREAM COME TRUE when you need a carburetor to design and machine into whatever you want with a venturi from 19 mm (.750 inch) to 22.2 mm (.875 inch). This carburetor comes as a gas carburetor but like all Tillotson carburetors it can be modified to use Methanol (Alky) as its fuel.
