High Quality carburetor made especially for Chevrolet 6 cyl engines to replace original Rochester model B/BC 1bbl factory carburetors.
Fits most 1937-1967 4cyl and 6cyl Chevy engines 192" up thru 260".
Some applications may require a different air filter than factory stock. Jetted with adjustable main jet, manual choke.

NOTE: May not fit the stock air filter.

This is a great choice for multiple installations, as the high speed side can be adjusted to prevent over-rich and manual jetting problems.

Air Cleaner
UNIVERSAL carburetors are manufactured to the highest quality standards, and contain alcohol resistant parts thru out, for long service life, under normal operating conditions.

Our fully UNIVERSAL carburetors are especially made to allow a wider variety of external adjustments. They have fully adjustable throttle arms, and externally adjustable high speed main jets. This allows the throttle arm to be indexed to any point you may need the arm to move. The externally adjustable main jet allows you to fine tune the high speed rich/lean mixture to the exact demands of your current engine. Variations in fuel lines, vacuum lines, choke cables and air cleaners may require re-routing or adapting of those items. Variations are usually not a problem on standard 1904 carburetors.

Carburetors are not returnable once fuel has been put through them. Please check carefully for fitment before installing and using any replacement carburetor.
