Soounds to me like you need the proper Honda manual for the adjustments, as to the standpipe officially you have to replace the complete floatbowl which i think is teh same as the 500 but the only parts book i don't have is the 550f so i cannot be 100% on that.
I was looking at buying brass tube and drilling out and tapping the bowl then screwing in a tube with loctite but that is all still in me ead.
The jet retainer frequently falls out when you remove the bowl as its teh bowl that holds it in tight

It confirms that the floatbowl, otherwise known as chamber set A or B, has a 323 middle part number making it the same as 500 four and all the US 550 K models Up to but not including the 77 K3

The tubes are very difficult to solder. I have found the most effective method is to smear araldite along the crack. I have one on my bike which was temporarily repaired in this way 8 years ago and still working fine.

OK, so i am replacing all the little O rings on the jets ( managing to do it with the carbs in situ). It seems like the floats in the 2 right hand carbs are just not cutting the fuel off at all so need a big adjustment. I now have a manual & it states the measurement between the top !! of the float to the base !! of the float chamber should be 22mm when the tang of the float is bent so that it is touching the jet. Could anyone explain to me in layman terms how this is measured ! Maybe a little diagram would help ! Also how could the floats alter so much in general use.
