Topic: What do you think of these carbs?

[bender01]

I didnt seperate mine from the bank. I have a rectangular drywall mud pan that I used to soak all four after the parts are out. Ive used simple green half with water and straight. I saved it the last time (straight) to re use it at some point. I also left the needle and slides in the bank and they cleaned up fine.

Sweet thank bender.  I went ahead and took 2 apart last night just to see how they look and they are pretty simple really.  I think I am going to try cleaning the whole thing with all the guts out and see how it works.  I figured if I let it sit in the simple green for a day or 2 then used my compressor on them really good then let them sit open for a few days that everything should be ok.  Anyways I will post some pics when they are done.  Again thanks for all the help everyone.

OK then, how i worked it out

(1) You can see the pilot air screws sticking downwards outside the float bowl

(2) you can see the carb top has a screw at the end

(3) Screw in main jet and push in pilot jet

Now all those also come on the 750 F2; F3 and Auto BUT

(4) No accelerator pump on No2 carb.

Those carbs are the ones with least detail available in any manual, the ONLY place i have found info is in the Genuine Honda Supplement for the 77/78 CB500/550 K3 and that is sparce with bad pictures

Ya that is on my list of things to do.  I want to get everything cleaned and put back together and then go through and run new hoses for everything.  After all the time I have spent cleaning everything I wouldnt want to have to go through and do it all over again.

While it is pretty lame to feed clean carbs with tank cr@p, The 78CB550 has a wonderful fine mesh filter on top of the petcock.  If that is still in good condition, an axtra inline filter is redundant, almost useless, and adds another maintenance item to routine replacement.  Also, due to the gravity feed fuel system, extra fuel tube routing (often required to add the filter) adds peaks and valleys that can make odd carb behavior as the the fuel in tank level gets lower.

those carbs look cleaner than mine, AFTER I cleaned them.
