Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
Compatible equipment / model
- Onan KY-series gasoline generators using 146-0881
- Cummins Onan RV QG 4000 gasoline generators using A041D744
- Onan MicroQuiet 4000 gasoline applications with matching specification and carburetor
Product Overview
A generator that sat with old fuel may crank but not start, surge without load, hunt as the air conditioner comes on, or leak from the carburetor. When cleaning will not recover damaged passages or a stuck needle, this replacement puts a complete metering unit back in place.
KY-series generators have model and specification-letter differences. Read the data tag and compare the choke, fuel inlet, mounting, and electrical connections; this carburetor is not for propane-only units.
This is an aftermarket replacement part and is not manufactured or supplied by the original equipment brand.

Frequently Asked Questions
Q: Will this fix every surging Onan generator? A: No. Low fuel pressure, intake leaks, governor problems, dirty cooling passages, and electrical load faults can cause similar symptoms.
Q: Does it fit propane generators? A: No. This unit is for compatible gasoline applications.
Q: Why does the specification letter matter? A: Onan can change carburetors and controls within the same KY family.
