A microwave is really too much and has a cyclical inductive load and tranmsformer inside. Which can cause deration of your generator output

Sounds to me like you have some water in the carby. To check this, loosen the little screw at the bottom of the carby bowl and catch what comes out in a cupped hand. ( you may need to put it on bricks to do this).
If you do have a globule of water running around in the petrol you catch, draining it here for a few seconds with the fuel tap on may be enough to fix it. I would always check the water trap on the bottom of the fuel tap at the same time though.
If this only works for a little while, you may need to remove the fuel tank and drain & dry it with a rag and stick.
Having said all that, I have had similar symptoms
to what you describe, caused by a spark plug, so that is another quick and easy thing to try.
Hope this is of some help.

I am having the same problem with my 1850 as well. I borrowed the cap off my lawn mower but the vibration was still pushing gas out of the top of it as well. I cut out a thick piece of rubber and put it inside the cap, that sealed the leak but now the engine dies after about 5 mins of running. I suspect that the cap is now too tight and that it is creating a vacuum in the tank. I am going to call Coleman tomorrow to see about getting a proper replacement cap, which I hear are available.

check to see if the cord is knoted up in the pulley. if not you either have a seized up engine or armature.

For most applications I recommend straight 30 weight oil. If you are going to be using it much at below 30 degrees F. then I would use 10w-30. Hope this helps you. Thanks.

Check for a hard lock-out (used to stop the generator from being started while refueling) otherwise your best shot is to take it to a small-engine guy with a max budget of $150.00 to avoid paying almost as much as for a replacement.
