Been gone on vacation and moving my son, but I have recently done a few other things. I cleaned the fuel tank....there was a little sediment, but no water that I could detect. I checked the fuel lines and put a new filter on and put fresh gas in with a fuel stabilizer. I checked the spark and it has good spark to both plugs. I sprayed some starting fluid in it and it fired on that, so I tried it with gas and it tried to start, but quickly dark smoke came out the exhaust and it wouldn't start. I noticed fuel at the inlet of the carb again and when I took the plugs out they were wet. When I turn it over with the plugs out, gas droplets come out the spark plug holes.

Where to go from here? It obviously seems to be a fuel problem. Didn't you say earlier it could be the carb? Do they just malfunction out of the blue like that? Is some air passage closed that floods the carb with fuel?

I cleaned the carb and all the parts. I used a small wire and compressed air in all the air passages. Then I blew threw each one with a plastic tube and they all were open and allowed the passage of air. The float was not waterlogged and the needle and seat looked like new. After putting it back together, now the generator won't run at all! It turns over and tries to start, but won't. The plugs look wet, but there is not all the raw gas coming out of the spark plug holes
or out the carb air intake like before.

I guess I will check the spark, but can't imagine that is suddenly a problem. I think it is time to remove it so I can access everything and either get a new carb or take it in for service.

I am going to take the carb off, soak it in carb cleaner and put it back together. The only thing I can guess is that it is a clogged air circuit in the carb or a
bad carb itself. Can't think of anything else. Nothing else would cause too much fuel, would it? I'll let you know what happens.

It runs the same with the air filter off. It does have a fuel pump-the manual I have says to check it with 12 volts to see if it clicks, but nothing about actual fuel pressure. I didn't check the main jet, but I can do that when I take it apart again. Everything looked fine with the float, but I have located the spec for the float level height, so I will check that when I take the carb apart, clean everything and reassemble it. One other thing-it has a fuel cut solenoid valve. Here is what I can find about it:

FUEL CUT SOLENOID
When the engine is turned off, it will make several complete revolutions before coming to a complete stop. Each intake valve opening will continue to allow fuel to enter the combustion chamber, but without spark occurring. If there is a hot piece of carbon in the combustion chamber, or in the muffler, engine run-on or after burning could occur. The fuel cut stops the flow of fuel to the carburetor main jet.
The fuel cut solenoid is located on the bottom of the carburetor. Electrical power from the generator activates the fuel cut solenoid when the engine switch is turned to the OFF position. The beauty of this system is that a battery is not required to power the system.
Once the generator comes to a complete stop, the solenoid will deenergize and a spring inside the solenoid will pull the needle away from the main jet.

That sounds like something that would keep fuel from the jet rather than too much fuel as it states. To test it, the book says to check continuity between the two leads and it should read 7.5 ohms. I checked it and it reads 6.9. It doesn't have a range, so I am not sure what to make of that, except that it is used to stop fuel to the jet. The generator does not run after turning it off, however.

It also has an adjustment for the pilot screw. I will set it to the standard setting, although the manual says to adjust it after the engine has warmed up to normal operating temperature.
Not sure what the pilot screw does....does that regulate fuel to the jet? I will give it a go tomorrow and set everything I can find to the specs in the manual and see what happens.

I took the carb off today and checked the float. Everything seemed normal-clean bowl, float pin was clean and not deformed at all. I didn't check the height of the float-not sure how to do that- but it appeared ok to me just looking. It dropped down a little when turned right side up and would be pushed up a bit when it floated on the fuel. I put it back together and started it up. It ran longer than before, but rich with lots of black/gray smoke and eventually stopped. I checked the choke and it functioned like it should-rotated to choke when the start button was pushed and held and then off when released. I noticed that there was droplets and a mist of gasoline coming out of the air inlet port from the air filter to the carb that I had not put back together. There was even gas droplets running out of the air intake inlet. When I took the spark plugs out, they were wet and when I turned the engine over a mist of gasoline came out of the holes also. So, obviously too much gas still. The choke appears to work appropriately and the throttle linkage also seemed to work fine. Ideas? Can fuel pump pressure be too high for some reason and push too much fuel through the carb? Where could all this gas be coming from.
Thanks again for the help,
