I bet there's a three digit number on the inner side. 341?

That is is not original paint, is it? Peculiar positioning of the brake actuator rod.

Make sure you have checked the appropiate partslist for your specific model. My CB500K2-ED, like the CB550K2, does not have these D washers anymore and has 7mm* instead of 8mm bolts.
* Tightening torque: 1,8-2,5 kg/m

Depends. What is the prescribed position and what is yours now. I've changed the needle's position (CB500) out of curiosity and there wasn't that much effect, just like a Honda mec had said. I'd stay close to the original settings.
Leaking O-rings on the main jets have to be excluded, as well as accidently reamed slow jets.
Aftermarket air intake can make a difference, aftermarket exhaust hardly at all.
The correct fuel level in the floatbowls can easily be checked by applying this method: http://forums.sohc4.net/index.php/topic,185754.msg2151647.html#msg2151647.
Without having read all the above, make sure air intake is unobstructed, the airfilter element is good, meaning not moist or fouled by crankcase fumes.

After a lot of poking around and swapping carb internals it turned out that the emulsion tubes had  worn a bit oval internally where the throttle slide needles go. 
[...]

Put some new needles and emulsion tubes in and the problem disappeared.

This is in contrast to what I experienced the other day. For a silly reason - to be explained later - I had the carbs on the table. I closely examined needle jets and needles. On reassembly I accidently have mixed up jets and needles - so they were not the pairs they were before, and to my surprise bike runs nicely. The same accidental mix up happened to float needles and their valves and again: no negative effects. These parts have been in service over 140.000km. Makes me wonder what parts have been in your carbs: aftermarket or OEM and the same question to which parts you have put in now.

I always use a T-handle and a 23 mm socket when cranking some millimeters a CB500 for timing. I estimate the risk of damage by removing the spark plugs far higher than cranking that WASHER, SPECIAL which, btw, is still the original... Things may be different with a CB750. I've seen more than once that problems that can occurr on CB750s, were bluntly transferred by experts to CB500550s.

Knowing the K3's cold start behaviour all too well, my choice would be the #42 jets... minimum!

So an ordinary grease gun should work?
Should I unscrew the nipple, check if it works and eventually clean it?

Thanks. The reason I asked: in 46 years of ownership I remember only two times I have managed to get any grease in there. I've been lucky I guess: bushing is still fine. I should add that Honda had modified the parts involved somewhat on later models like mine, but I don't know if that has played any role.

Does any of you know a greaser that will fit my central nipple? https://www.cmsnl.com/honda-cb500k2-general-export_model50441/nipple-grease_9620180000/

Personally I wouldn't bother and have the three fuses floating. I had to add two fuses: one for the horns and one for an auxilary wire. Just cut the wires and insert the fuses. The wires are short and stiff enough not to wander about.
