When an Onan KY series generator starts running rough, flooding, or won't hold idle, a worn carburetor is a common culprit. This Cummins/Onan A042P619 carburetor is built as a direct replacement for KY series Spec DL generators, restoring proper fuel metering so your genset starts easier and runs smoother.
Confirm your generator's model and spec letter against A042P619 before ordering, since Onan carburetors vary by series and spec revision.
