onan generator carb kit

When I lived in west central FL, there was a fuel system shop that would rebuild ONAN along with their bread and butter auto/truck carb work. There's a similar operation where I am now in NE FL that won't. Just auto/truck. If you live in a populous area, you might be able to call around and get some parts or somebody to rebuild it. ONAN itself discontinued carb parts/kits. I consider myself lucky to have gotten that rebuild. I'd tried several times to clean it and never could. The shop had ultrasonic equipment that got the sticky old fuel deposits out.
