FAQ

This kit is designed for Onan 5500 and 7000 Grand Marquis Gold series gasoline generators. It is compatible with models HGJAA, HGJAB, HGJAC, HGJAE, and HGJAF, including specific variants such as HGJAB-901D, HGJAB-900, and 5.5HGJAB-6755K.
This carburetor kit replaces several OEM part numbers, including 541-0765, 146-0774, 141-0982, 141-0983, A043B781, A041P558, and 48-2042.
If your generator is surging, hunting for idle, struggling to start, or running roughly under load, the carburetor is often the culprit. These issues are frequently caused by old fuel sitting in the system, which creates varnish and clogs the internal jets that are too small to clean effectively.
No, there is no individual repair or rebuild kit available for this specific carburetor. Replacing the complete unit is the standard and most reliable method for restoring proper generator performance.
Before installation, ensure your fuel lines are in good condition and not cracked or brittle. It is also highly recommended to replace the fuel filter and drain any old, degraded fuel from the tank to prevent the new carburetor from becoming clogged immediately.
The installation is straightforward for those familiar with basic mechanical repairs. The kit is designed to fit directly without requiring complex adjustments. Ensure you have basic hand tools, such as a socket set and screwdrivers, to remove the air cleaner assembly and the existing fuel connections.
