Bring a worn carburetor back to specification with the Walker Products Carburetor Repair Kit 15433, built for the Holley 1-barrel Model 1904 carburetor. It installs as a direct-fit rebuild kit for a range of vintage International applications, including the 1957-1958 A100 Truck, the 1961-1965 International Scout 80, the 1966-1971 International Scout 800, and the 1961-1964 International M Series Van — see the Buyer's Guide tab for the full list of covered vehicles.
- OE-matched contents: gaskets, seals, and metering parts sized to help restore proper fuel metering and fit.
- Ethanol-ready: engineered for use with today's fuel blends, including ethanol-containing fuels.
- Rebuild-ready kit: supplies the wear components needed to rebuild the Holley 1904 to OE specifications.
Carburetors wear over time as gaskets harden, seals shrink, and metering parts erode. Rough idle, hard starting, fuel seepage, or dropping fuel economy can be signs the carburetor is due for a rebuild. If a worn carburetor is the cause, installing this kit replaces those degraded components to help restore proper fuel flow, throttle response, and idle stability. Diagnose the source of the drivability issue before servicing, since these symptoms can have other causes.
