SOURCE: kohler 12kw generator starts but shuts down after 3sec

Your gas pressure is too low and you may not have a large enough supply pipe. You need at least 10 inches of water column with the engine running to operate an LP vapor fueled engine. Because the engine is starving for fuel, its governor opens the throttle to WOT (so it goes to high revs) but there isn't any fuel to make horsepower with so the output voltage falls and the undervoltage alarm trips.

SOURCE: Generator pulsates when its running 12-KW natural gas

You've described the symptoms of a dirty air cleaner, surging throttle (the pulsating), oil getting sucked up thru the breather into the intake (the why you have to add oil).
When you check/change the air cleaner you should also have a look at the spark plug, the dirty air cleaner forced the engine to burn some oil and that may have left junk on the plug.

To make it easier to read the oil level on a dipstick, try dipping the stick into a little water. When you draw it back out of the water the contrast between the oil covered part of the dipstick and the water covered part will be a little more obvious. Sometimes looking at the backside of the dipstick is better too.

I been using gen for over 20 years on my farm as backup for my solar system and one issue the haeds...many users forget or no one tells them that they need to adjust the heads after every 40-50- hours and any changes in the setting will not allow the grn to start ot it will run for a few seconds than die...look for the exact seerting of the in and out and check tghem and see if that help...good luck. remmber in winter you need low grade oil not high or use synthatic better.

SOURCE: natural gas generator will not start. 4 years after installation.

very likely a fuel problem. First pull the air cleaner cover off and try choking the engine by putting your hand over the intake partially choking it. If this don't work then go Down on the bottom right hand side behind the battery you will see a fuel regulator on top of it is a fuel solenoid with 2 wires coming off it. Below the fuel solenoid you will see 2 -1/4" pipe plugs one on top of the other. If you pull the top one out and gas comes out then you have fuel up to the solenoid. If you pull the bottom one out and crank the engine then you should get gas out of the bottom one. If you don't then make sure you are getting 12 vdc to those 2 wires during cranking. If you do then You are going to have to pull the 4 screws out of the solenoid and pull the solenoid off and make sure you the seat on your solenoid valve is not sticking. If all this checks out and you are getting fuel out both 1/4" pipe plug holes, then you will need to see if you have a spark at the spark plugs, if you don't then something is shorting out your ignition coils. Disconnect wire 18 from its terminal located above the oil cooler. If the engine starts and runs with this wire disconnected then you need to trace this wire back to the control panel and see whats causing it to ground out.

Let me know if this helps.

SOURCE: How can i fix my nixon gasoline generator

Hello, yes this sounds like a small blockage in the carburetor,
My first stem would be undo the carb bowl and clean this out, also make sure the float works ok and shuts the fuel off when in the up posission..
strip and clean the carb but pay attention to the screw what holds the carb on, not sure if this type has small holes in what lets fuel into the engine? also where the screw holds the bowl on, inside there holds another jet, this gets blocked, make sure its clean and you can see through it..
Make sure you usse the correcy size screwdrivers as these brass screws split very easy and can be a pain in the *** to find replacements..
if you need any more assistance send me a msg.. thefueltank@hotmail.com
