Review: Carburetor for Onan 4000 generator - Good quality , requires fine tuning after installation 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. ## Features - FITS: Onan cummins microquiet ky series 4000-Watt 4KYFA26100 4KYFA26100P 4KYFA26100K - Replace Part Number: A042P619, 146-0785, A041D736, 146-0635, 146-0703, 146-0742, 146-0803, 146-0743, 146-0759 - CARBURETOR REPLACEMENT: You will get the fairly reliable and durable carb to help deliver optimum engines performance and to give your onan 4000 K generator the new power and torque.
