If true, did you remove the piece 32 (JET SET, PILOT (#35) (Honda Code 1441609)? With piece 32 removed, you can insert a flat screwdriver in the throat of the carb, and using the flat side of the screwdriver, push the piece 12 down.
When looking at the diagram, find the top of 12 (emulsion tube) that tip will protrude into the inside of the venturi/throat of the carb..Remove 31 (jet) with a screwdriver. Just use the flat part of the screw driver and push 12 from the inside of the venturi. ..It will slide out enough to pull it out where 31 (jet) was screwed into.

I was able to fix my EU1000i by cleaning the carb and adjusting the fuel pilot screw, #5 in the diagram. The pilot screw has an anti-tamper cover on the screw that must be removed. The cover is glued on with green Loctite. Just heat the cover with solder iron and pry off. I had the governor bounce until I backed the fuel screw out to two turns and the generator ran smooth on the eco mode. The carb must be removed to make and adjustment to the pilot screw, so track your adjustments, I went ½ turn until the engine smoothed out, then ¼ turn fine adjustment. This is probably an adjustment that every Honda generator needs.

This morning I finally got some time to goof with my carb some more. After soaking it in good ole' WD-40 for 2 hours I was able to push the emulsion tube out with very little effort with a small flat head screwdriver from inside the throat. I then finished cleaning the entire card, changed out the spark plug, reassembled everything...three pulls and it starts and runs like new...no sputter, no miss...it's back to perfect. THANKS TO ALL OF YOU FOR CONTRIBUTING IN THIS THREAD!

Best news this year!!!!
Did you find anything in the tube? Was the end of the tube that protrudes into the venturi area discolored?

The tube had your typical gluey crust of old hardened fuel clogging almost all the holes. I cleaned all the holes using a mini drill set from harbor freight. No discoloration anywhere though.

Wayne (Reddog1) and I did a mod on our honder's last year...
We installed an extended almost clear fuel line and added a glass filter found in auto parts places. He has experienced numerous carb problems, me, 3 times. My Honda is about 4 years old.
Last week we did an inspection of our fuel system....
His had a weird sediment, mostly liquid but like a syrup in the loop of the fuel line along with some in the filter. There was also some fine contaminants..
We put the gas/syrup in a clear bottle and removed as much of the gas as we could....The syrup was thick as molasses....We do not have a clue what it was but he was thankful that it had not entered his carb.
Wayne's honda probably has more hours on it that most of us...It was his primary source of shore power for a few years before he got solar.
The discoloration I was talking about is that the tip of the emulsion tube that protrudes into the venturi is gray in color.
We saw that with Wayne's tube....Initially his was difficult to remove if I recall.
The syrup really bothers me....I have older Briggs Stratton engines in everything... 2 riding mowers, rototiller, pressure washer, chipper shredder etc....I have not had a carb problem on any of those devices....I have never drained the tanks to take a look.
I have many old VW aircooled carbs that I have taken apart to rebuild..See lots of dry powder corrosion, never anything like what we saw. These carbs were all pre-mtbe/ethanol.
I am totally at a loss as to what that was, never seen anything like it. Being the cold wimp that I am, I do not want to disassemble the Honda to really give the tank a good cleaning, till it is warmer outside. When I do take it apart, I hope to remove the OEM fuel filter, and install a fuel tank drain at the same tear down.
I am very pleased with our add-on fuel filter. My add-on filter definitely trapped water, and that was one of the objectives. I might add, the syrup had not reached the add-on filter, but did get through the OEM filter.

One of the things we did, when vintage car racing, was run the used oil through a testing facility to find out the status of our expensive engines. We used AMSOIL testing for our needs. There are many testing facilities out there and possibly you could send in a sample of this "syrup" to ease your mind in what it really is? Yes I realize I said Oil and your comment is for fuel, but when testing they are really the same and a test will narrow it down to the origin.
Thanks for the suggestion b. I am going to see if I have something in the Honda tank first. There was not enough to get real excited about, but does raise an eyebrow.
