Review: Works surprisingly well - My original carburetor was leaking out the altitude adjustment knob, didn't want to mess with finding the correct o-ring for the needle and wanted my generator to run without burning the house down. Installed on a late 1999 onan 4000 generator model 4ky fa26100j, fit perfect, easy instal (about one hour). Runs much better than before, no leaks, and has a fuel bowl drain valve that my original did not have. The altitude adjustment doesn't appear to do anything, however I don't know the history of the gen and after years of running on a dirty carb it maybe running more the 3600 RPM and it likely needs linkage adjustment. Good buy for the price. I think these "knock offs" get a bad reputation because they are a last resort and the generator linkages have been messed with so much to try and get the old dirty carburetor to work and ends up way out of adjustment once the new one is put on and they don't run correctly.
Review: Onan generator fired right up with this replacement carburetor - It's always wise to be weary of a non OEM replacement carburetor. In this case however, and OEM carburetor costs a heck of a lot more than this replacement does. I was able to quickly get this into my Onan generator and it fired up within 4 seconds. Interestingly, I put the linkage on incorrectly and so after the generator warmed up it would not stay running. Once I recognized my issue I flipped the linkage and everything worked perfectly with minor adjustments to the governor. Now my generator is operating like new and able to seamlessly adjust from zero load to almost 4,000 Watts, the max my generator supports. I cannot speak to the longevity of this replacement carburetor however if I get a few years out of it it's well worth the cost. I will be shutting off the fuel source and letting the carb run dry instead of turning off the generator as this should keep the carb components cleaner and last longer. I recommend you do the same. Installing a shut-off valve is simple when replacing a carburetor.
