Custom Orders

We can bore the venturi of the HB carburetor out up to approximately 38mm.  Contact us  at sales@tillotson.ie for special orders at a price similar to the HB-12A.  Note that in requesting a size for an HB, we generally recommend sizing down the venturi 2-6mm from a standard float carburetor you might otherwise use.  The high-velocity air flow of the HB’s generally allows the smaller venturi to provide the same top-end performance with substantially better bottom end and acceleration.
