Product Overview
An Onan engine that sat with old fuel may crank but refuse to start, surge after warm-up, flood, or run only with the choke partly closed. Once compression, ignition, fuel supply, and intake leaks have been checked, a contaminated or worn carburetor is often the repair holding the machine back.
This replacement is meant for the listed twin-cylinder engine families when the original number, linkage, choke arrangement, fuel inlet, and mounting pattern agree. Engine specification numbers matter because Onan used different carburetor calibrations within similar-looking engines.
Key Features & Performance
- Replacement carburetor for selected Onan opposed-twin engines
- Addresses verified fuel-metering wear and varnish damage
- Supports normal starting, idle, and throttle response after setup
- Matches multiple commonly referenced Onan carburetor numbers
- Aftermarket option for aging generator and equipment engines

Frequently Asked Questions
Q: Can old gasoline damage the carburetor? A: Yes. Evaporated fuel can leave varnish in jets and passages and can damage seals.
Q: Will this fit every P220G engine? A: Not automatically. Onan specification numbers and linkage layouts vary, so the original carburetor number must match.
Q: Should I replace the fuel filter too? A: It is wise to inspect the tank, hose, pump, and filter so contamination does not immediately reach the replacement carburetor.
