Repairing a Honda eu2000 Generator

Hi.
The engine wore out (finally) on my little Honda eu2000 generator after about 12,000 hours. I took it to a repair place and they want about $800 to fix it. A new one is $895.
So, does anyone happen to know if there is a Honda engine that will fit it? I have not taken the inside plastic cover off yet but according to the repair guy it's just like a GC or GX engine, at least as far as the slant engine design etc.
If the only choice is to rebuild it then I'll get the shop manual and a micrometer but I would consider putting a cheaper engine in it (Honda GC etc) if it can be made to fit in there. So far all I know is that it's a 3.5 HP engine.
Thanks.

Just open it up and see what kind of GX series it is.
You can go on ebay and do a search for the model number.

The only reason it's still together is because I don't have good place to put it and work on it but it's looking like it's gonna have to get it's own workbench. I'm no master mechanic so this is probably gonna take me a while.
I would have guessed it was a GX engine too but the guy at Honda (in Georgia--I called them) said it had a steel cylinder and I thought the GX series had cast iron. I also thought the GX had a timing chain instead of a belt but I guess I'll have to go pull the valve cover off my GX270 and see.
It sounds like the tricky parts, assuming I can find a direct replacement, will be the DC producing magneto/alternator and the electric throttle control. Maybe they will just bolt right on. I was hoping to gain from someone else's experience but it looks like I'm gonna be first.

Actually I just checked hondas website. That unit has the gx100 engine on it. Not really a common honda engine.
If its similar to a gx 120 on up you can do a cheap swap.
You'd need to make sure that its roughly the same dimensions as other models.

Thanks Tom! Where did you find that info? I looked and didn't find anything on the engine.
I reckon it won't hurt anthing if I have to put in a 4 HP instead of 3.5 or whatever. As long as they are the same outside. Some of the guys selling engines on eBay have all the specs, pics, and dimensions right on the listing. I'm now going back to Honda's site and see if I can find what you found...

Maybe it is just advertising, but they claim the engine and generator are integrated; so getting a generic replacement would be impossible.
Cool that you got 12,000 hours on it. I have 120 on mine.

which is rectified and fed into the inverter. I'm hoping it's removable. I called Honda (in Georgia no less) and they basically told me there is no short block available and a new engine would cost almost as much as a new generator and that rebuild was basically the only option.
I think part of my problem is this is one of the first ones to ever wear out. I guess that's good ;-)
I bought a new one last week and it already has 100 hours on it. Someday I'm gonna get hooked up to those wires they got on them poles and won't need to use it so much any more.
