The Y200 Zenith 28 style replaces 1 barrel downdraft carburetors on 140 – 300 CID 6 cylinder applications.
This carburetor is a direct replacement for Carter W-1, Rochester Model B and Zenith 28/228 carburetors used on Chevrolet, Chevrolet Truck, GMC and IHC applications with a clamp-on air cleaner. Does not fit air cleaners with wing nut retainers.
Also suitable for replacing Carter 1 bbl carbs such as the Carter BB, WA-1 and WE.
New, not rebuilt, replacement 1 barrel carburetor for 140-300 CID 6 cylinder applications. Features manual choke, universal type linkage and clamp-on air cleaner mounting.
Ethanol compatible: features Viton fuel inlet valve and brass accelerator pump.
Choke side showing manual choke and choke cable bracket. Throttle cable bracket also visible
Air cleaner mounting is standard approx 2-1/4 in. size. Integral fuel strainer. Inline filter is also supplied..
The throttle arm can be turned 180 degrees to accommodate various throttle linkages.
Vacuum advance port is provided.
The slotted flange accommodates common mounting bolt spacings. Main jet is fully adjustable.
In the table below, Direct Fit means replaces the original without modification; Universal Fit means minor differences, eg fuel line in different location etc.
Note that some carbs have the throttle shaft and choke shaft parallel (style 'A'). The Y200 has crossed shafts, so the choke cable may need to be moved slightly from stock in applications that used a 'B' style linkage.See the article here for more information.Â
