I think I tracked it down:

Holder (governer) 16512ZL8000 $1.86

from good old Peninsula Honda .. I called my semi-local dealer (about 50
miles away) and they wanted $3 and didn't want to ship it.

Man had I known they were that cheap i'd have swapped them every time.
THink i'll get 4-5 of them to have spares.

Boy Honda sure is stingy with the parts lists. It'd be so easy to PDF
all that stuff and have it for download but they want you to shell out 8
bucks just to find out what the dang part numbers are.

thanks again Ulysses

Tell us more! How hard is the part to swap and how often should it be
done?

Hey, I really hope you are right about that, but one good hurricane can
change those numbers in a hurry. Also, (and more worrying) some plastics do
not need use to degrade.

In order to replace the so-called governor gear you have to remove all of
the red plastic (not so hard after you do it a few times), remove the
carburator/air cleaner assembly, remove the black plastic from around the
engine, probably remove the exhaust manifold (don't remember offhand), and
remove the engine mount at the bottom. Then you have to split the engine
case. The gear is attached to the engine case so all you need to do is
drive out the holder shaft with a drift or whatever, put on the new gear,
and drive it back in. Use high-temp black silicone (no gasket) and torque
to specs (I couldn't find the exact specs to I did it according to the specs
for a siimilar engine but I don't remember offhand what that was). I like
to torque to about 3/4 the specs, let the silicone set for several hours,
then torque it the rest of the way. While looking through the oil
fill/drain hole pull the rope gently a few times to make sure the gear is
properly aligned with the crankshaft.

My experience is that when the gear breaks the cylinder is destroyed very
shortly after. If your engine is buring oil it might be too late. But, if
the gear is replaced before it breaks I can imagine that as many as 20,000
hours might be possible on an eu2000 if it is generally run in Eco Throttle
mode.

Basically you have to take the whole bloody thing apart so it's a pretty big
job but in my opinion it should be worth the effort. If Honda would make a
governor gear from forged steel it might last forever. Having taken apart
the eu2000 engine and a Honda GX engine it looks like the GX should last
forever and the eu2000 should not last anywhere near as long as they do.
Honda told me the eu2000 uses a GX100 engine but from everything I've seen
it sure looks like a GC engine. The bigger GX engines are OHV types with
pushrods. The GC engines are OHC with timing belts and plastic cam gears.

It's possible to see the plastic governor gear on the eu2000 by looking
through the oil fill/drain hole with a small flashlight. If it does not
look straight then it might be broken. On my second eu2000 the fins from
the gear had broken off and rode up the timing belt and landed up where you
adjust the valves.

Does anyone know Honda's recommended schedule for changing the timing belt?
I suppose that would be the time to change the gear too.

STOP! WAIT! That *can't* be the governor gear for that price. It must
be the shaft that it rides one. If you order the wrong part from Peninsula
you will have to pay a re-stocking fee and return shipping.

Besides that it occured to me this morning that I have a governor gear that
is almost new that I'm never going to use. I also have a nearly new belt
and cam gear. I tried to repair eu2000 #1 but since the cylinder was so
worn it didn't do any good and these parts have only a few hours on them.
They can be had for a song (or the cost of shipping and they don't weigh
much). Maybe you have something to swap?

Ulysses' eu2000 Maintenance Schedule: Change the governor gear every 5,000
hours. Check the belt for cracks at this time and replace if necessary.
Check the cam on the cam gear for wear and replace if it shows more than
about 1/16" of wear.

This is based upon my personal experience. The governor gear (which is NOT
a governor, just an oil splasher) on my first eu2000 lasted about 12,000
hours. The second eu2000 lost it's gear at about 7200 hours. So I figure
5000 hours should provide a safety margin.

I also put a couple of drops of oil on the two "handle" screws at the top of
the plastic case and also on the two long bolts that hold the bottom
together. I had to use a screw extractor on one of the handle screws and
rebuild the nut-holding section on the bottom because Honda figured out how
to make screws get tighter due to vibration.
