honda eu2000i generator doesn't start

Probably normal.
If it has a lot of hrs remove the muffler and check/clean the spark arrestor screen.
I use a mini torch and heat them til they glow red after removing the larger stuff.
Glad it's running "again", hopefully tgis time it sticks .

Me too. What about gunky stuff on the valves is there any way to clean the inside without disassembling the engine ?

How can you see gunky stuff on the valves. If you can see it clean it off!

When I believe there are large amounts of deposits i will use additives to help remove them, but I don't want them to break loose to fast.
I will use small amounts of sea foam or chevron techron. Also use premium fuel with good additives, not sure which that is in your area. If it will be sitting (generators usually do, but not sure since you said it's high hrs) I would run only ethanol free fuel in it. There is a smart phone app called pure gas that shows where it's available in your area. It can normally be found at all marinas and airports but watch the octane as the high octane is not the best for this application.

If it is a relatively clean engine and it had carb deposits/fuel that was bad that's another story. I run the fuel tank down low and add about a 1/4 can of seafoam. I leave engine running and once you start to smell the seafoam burning let it run for a couple more minutes then shut it off. Wait about half hr then start it up and run it til it is gone. Refuel then start the engine and let it run til there is no smell, then another 10 minutes.
Seafoam will swell some parts and should not be left in the fuel system mixed as I am suggesting.

I actually meant I could see it through the spark plug hole . But I used some seafoam but just didn't use quite that much

I see .
It's normal to see some especially on an engine that has a lot of hrs. I would tell them to be sure to use a good fuel with additives in it and I would not worry about it. Those motors are a lot of work to get out and torn down. I would tell the customer (if asked) that it is not worth it. When one has a lot of hrs on it they have already gotten their money's worth. Time to sell it for parts and buy a new one vs the added expense of paying you/me to repair it(which that isn't a repair but more preventative maintenance), it's not a good deal for the customer. Besides it's still running well now and probably will be for yrs to come.

Well it's fixed now the carb was a little dirty and the inside of the engine had a lot of carbon in it . What would be the cause of that ?
