The float needles were both clean, the seats were clean, but the floats were both (old carb and new) plastic with no way of adjusting. When it runs right there isn't even any hunting going on, only smooth even rpms.Īfter I decided things were as clean as they were going to get, I started down other paths. I checked and watched the choke and everything was clearly staying open and not an issue. so I knew it was getting everything it needed to operate smoothly, but something was getting in the way. The flooding had to be minor, besides I could get it to purr short term…. So, I figure it had to be some odd event that I'd need to pin down. level with fuel hooked up and flowing with NO LEAKS OR LEAKING. have same issue with flooding? I cleaned the needle, seat, float, bowl, carburetor jets, tried sprays, and additives. Same issues with it - flooding with the obvious rich combustion, smoke, and eventual shutdown.Ĭarb. a number of times and things improved, but no smooth running. Genset sputtered and coughed, but did not run. This is not a impressive generator, I know, but I can get it to run before it floods and stops. I have learned a great deal, yet have not overcome an issue that my generator has. Running some Stabil through the fuel system before storing them, extends the fuel stability and keeps the fuel delivery system, oiled up so to speak.Hello! I am new to posting on Sparks but enjoy digging and lurking for information. Running some kind of carburetor cleaner through this kind of system keeps them in operation longer.

This is the area that is most effected by the new ethanol-containing fuels. When it goes through the fuel system it lubricates the internal parts and helps to revitalize the needle and set. Rust and dirt builds up in the bowls over time and setting is not the best for them either. The other is Stabil, although this is more for storing fuel and engines for longer periods of time. I tend to lean towards Lucas Carburetor and injector cleaner. cleaner through it and just let it set for a day. could be its gummed up as mentioned by Brett. They do have some fine adjustments of the internal parts that need to be set properly for the Carburetor to work properly. You should have the Make, Model and serial number of the engine to help getting the parts. There are numbers on them that help the Small engine shops locate rebuild kits. Zenith is quite common on many Gas generators and your year unit could be one of them.

Talley, There will be a name on the carburetor, generally right in the casting.
