Works surprisingly well
Color: Carburetor with Gaskets
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.

Onan generator fired right up with this replacement carburetor
Color: Carburetor with Gaskets
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.

DO NOT BUY! It's cheap and doesn't work.
Color: Carburetor with Gaskets
Absolute junk. It didn't work at all. When I called up a small engine mechanic to find out what I did wrong, the first thing he asked was "did you buy a carburetor off of Amazon? They rarely work!" Needless to say, I'm returning this carb and buying an OEM version. DO NOT BUY!

When you need it, you have got to have it
Color: Carburetor with Gaskets
This little jewel is the epitome of job creation. They make a Carburetor that does not come apart so instead of selling you the parts, they just sell the whole thing. As the dumbing-down of society continues this Carburetor is doing it's part. Is it a million dollars? NO, but it perpetuates the concept that we don't need to know what goes on in there, just swap the whole thing out and add it to the landfill. Anyway, these are really hard to change out if you have big hands. Onan crams everything in a little box and you have to take everything out of the way in order to work your way back to the Carburetor. I needed an angle mirror deepwell sockets in a shallow space and a lot of luck getting those bolts back in there where no man could go. I am a miracle worker and managed to resurrect the Genset one last time. Its a cheap fix and it works, but I don't have to like it.

Working great in my 1999 Onan 4000 generator
Color: Carburetor with Gaskets
I took a leap of faith on this as reviews are mixed across all of these aftermarket carbs for the Onan 4000. Given that the OEM carb from Cummins was over $1,000 and on back order, what choice did I have? Very pleased to report that my generator is running perfectly, better than it has in years. At this price point, I thought I would just try another one if this one had failed. No need which is great. Do make sure you have the linkages hooked up correctly before you condemn the new carb. I made this mistake initially and corrected it. Lots of help on Youtube out there.
