Review on 🔧 High Performance Partman Carburetor - Compatible with Onan Cummins A041D736, A042P619, Microquiet 4000-Watt 4KYFA26100 Generators by Dan Sturm

$70 vs $300+ and it worked great on my Onan 4000K series. Getting the old stuff out is a bit difficult. You must first remove the air filter and bracket, then work blindly in the throat area to find the two long screws that hold the carburetor in place (10mm screw). I used a medium extension with a 10mm flat head and "found" the head of the bolt, then inserted a ratchet and connected to the extension. Once you loosen the two screws, "slide" the carburetor and gasket toward you with the gasket. It's tight, but it will come. Difficult to fit a new one with gaskets, gaskets, carburetor etc, but doable. An extra pair of hands will help a lot. Using a small screwdriver, allen wrench, or punch, poke all holes from the "backside" (ie, right to left). This will align the holes and then insert the screw from the left side (ie from the front). Now my 12 year old generator runs like new!
