Could y'all help me find the correct model identification for this generator, i can not find a tag or anything to get a correct Model number so i can get the right parts diagram. I've stuck my head all around this and can't find a specific number. is there a specific spot to look? it's driving me wacko

Thanks will have a look there.
I've got it running decent now, apparently it had the Honda/NGK spark plug problem, put a new one in and she runs good now, but surging under load.

Well, an issue cropped up. the electronic choke is taking about 20 seconds to switch off, in other words, the engine runs rich for the 1st 20 seconds, then the choke opens., then i see the choke arm switch to fully open, from closed.
i can push it to open, it runs normal, then let off, and it goes right back to choke.
