The Tillotson HL or HR series carburetor can be converted to high volume double pump setup to allow the use
of methanol ( alcohol ) fuel,  or just to feed more petrol to thirstier engines.

The parts required to do the conversion are ...
    1 only    #91A-351    Fuel strainer cover
    1 only    #198-305    Fuel pump body
    1 only    #91A-303    Diaphragm cover

    1 only    #DG-4HL    Double pump gasket and diaphragm kit
    6 only    #15B-343    Long body screws                                   Total price for all of above is   $134.00

In addition we can bore carbs to larger throat sizes, or for larger throttle bores, or re-drill the fuel passages to suit
methanol ( alcohol ) fuels for various applications.   Go here to see our workshop services to do this for you.
