Topic: Anyone have success running 022A Carbs on a 1976 Cb550 (087A carbs originally)?

[rocs]

I just removed the carbs off a new project 1976 Honda CB550 I picked up and the outside look brand new but the inside appears to be completely shot. I think they are beyond salvageable.

I managed to find a set of 022A carbs and was wondering if these would/could run with no issue? I did try a set of 022A's from my 74 cb550 just to get it running and it did start up. I didn't get much further than that.

Should I switch any jets or do any modifications?

[harisuluv]

Yeah, they should be fine.

[Deltarider]

They should work OK. The 022A was on the CB550 and CB550K1, the 087A on the CB550K2 ('76). Main and slow jets are the same as is the needle set. There could be a difference in needle position, could. Strangely enough we find a different part number in the parts list for the airscrew, 16016-323-004 for the 022A and 16016-390-004 for the 087A. If this is really true the 087A has the same airscrew as in the 069A carbs that are found on the CB550F models.

Unless there is corrosion, they are completely rebuildable.

Care to sell them to me?  I've been looking for an unmolested set to determine the physical difference between 022A and 087A carbs.

No reason that I know of why the 022A won't work fine on the 76.  I think the 087s were a small step toward the looming EPA compliance requirement, possibly just the solid tipped pilot screw.

Cheers,

Thanks for the help guys.

TwoTired, I will post a pic of them in here to show you the condition. Here is a picture when I first removed the bowls. I have soaked them in PineSol for about 36 hours however. After that I was able to remove 3 or the 4 float pins. The last one seems to be stuck. I am still trying to remove them.

More pics to come after the soak. I still need to take some.





Floats are damaged and bent and so are the float needles. I can provide higher resolution if needed.

Any opinions? I really would like to keep the original carbs if possible. The bike it 100% original and looks like it rolled off the assembly line yesterday. I have never seen a cb550 in better condition yet. I think its cleaner than the one that sold on ebay last week at $4500 if anyone followed that...

A shame that someone let gas sit in them for so long.  I can tell that the outside is in good condition from what little I can see, no rust on the linkage, plating still in good shape.  I've seen worse but I wouldn't hold my breath on those.  When gas gets to that white powder stage it's like concrete, it's not coming off.   Just by looking at them, I would be worried about excessive pitting or corrosion in the float chamber.  Specifically the main jet tube, very possible you might not have enough "meat" left to get past the main jet o-ring. 

At the very least you have some good parts, you might be able to save the internals.  At the very least the linkage looks good, they are often broken meaning it is moving freely side to side. 

[TwoTired]

That wasn't just gas in the carbs, there was water in there, too.

As was said, if the main jet towers aren't too corroded, they are saveable, with some work and patience.  I have rebuilt worse, even with corrosion.

I'll retract my buy offer based on the pine sol abuse.  That stuff eats metal as well as the deposits.

Told you they were bad. I did a 10-12 hour pinesol soak and tried to get them to clean up and then did a 24 hour after on top. They were definitely a used and at that point I didn't have anything to lose.

I wouldn't feel comfortable selling unless they were for analyzation purposes. Like an ither member above mentioned, I'll just use them for parts

warning....





At least the parts are great on it. The carb bowls are flawless and shiny as well as the top caps(?) among other things.

[harisuluv]

I'm afraid out darkest fears have come true, alas.

[TwoTired]

Could you show us a picture of the pilot screw removed from the carb body?

[Nikon1975]

Can you fit the 22 on a cb500k1 ?

[TwoTired]

They are a physical fit, yes.
Some internal parts are different.

It matters if the induction and exhaust components are stock or aftermarket.

[Nikon1975]

Exhaust is a 4 in 4 by busso, equivalent to original. What do you mean by induction ? ( not a native speaker) if you mean airbox and filter are also original

[Stev-o]

What do you mean by induction ? ( not a native speaker) if you mean airbox and filter are also original

Yes, also known as intake.

Aaahhh... Busso... could you post a picture please? Are they like these? https://www.youtube.com/watch?v=uBty0JrkmCQ

They have #38 slow jets in stead of #40 that are found in the 627B and 649A carbs. BTW, where would you find 022A carbs in Europe?
You are aware Honda made an error in the 500/550 Shop Manual on p.165?
Over the left column in the Carburetor setting table you should read CB550 and not CB500.
Question: I vaguely remember having seen a photo of the Austrian Tourist assistance (AA or ADAC) patroling on CB500s.
Did they really in those years?

yes

[Nikon1975]

Mine are this. I bought the carbs on e-bay, to have a spare set.

So, can they fit?

D.

[Deltarider]

They'll fit.
