Carburetor Carb with Gaskets for Onan Cummins Generator & Microquiet 4000-Watt 4KYFA26100 4KYFA26100P 4KYFA26100K Replace# A042P619, A041D736, 146-0785

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.

Came with everything you need and works great.

Waited too long due to medical issues to install. Ran 6 times before refusing to run. I had to take to Cummins, which confirmed it is non functioning. Don't buy this. It's cheaper for a reason.

Item worked great

Great product. Just what I needed at a great price & quick delivery!

It was a pain replacing the older carb, but this new one was identical and fit perfect. I had my doubts that my generator would actually work, because I really did struggle installing it. To my surprise, it fired right up. Its been 4 months and I run it for about 15 minutes once a month since it is now winter. My generator is a ONAN QG 4000.

It didn't work on my Cummins 4000 generator after it was installed. The repairman removed the new carburetor and used parts from it to fix the old one he took off. The generator now runs fine.

Not difficult to remove old carb and install this unit. Seriously recommend watching a few Youtube videos for helpful hints like use your phone camera to see the bolts in the air cleaner assembly and use a dab of form a gasket to hold gaskets in place during assembly. Genset fired right up and did its job after adjust for altitude here in NW Arizona.Only negative was the fuel filter, not the correct type for my Cummins Onan 4KY. Save it for your lawn mower.
