gs550 float bowls

[Guest]

Hi i have just puller the carbs of my 1980 gs550 and stripped them it has not been going for ten years.managed to get the jets out and cleaned all the ports clear except the choke circuit in the float bowls.I cannot get them clear will try to acid dip them.I have a spear set of carbs of a gsx1100 and the float bowls are identical except for the letters stamped under the bowls gs550 bowls have d stamped and gsx1100 have b stamped anyone know what these letters mean please .

to clean the choke circuit I use a #10 thin guitar string. Couple of bucks at any music shop. To loosen the crap in them I have used PB Blaster soak for a few minutes. Careful with the PB. It attacks and ruins any rubber it contacts. Then I try to push the guitar string through from the top or carb body side. Once I get the guitar string through I'll use plenty of carb/brake cleaner, squirted from both the inside of the bowl and the top side until I have a good stream of cleaner from both directions.

As for the letter on the bottom, sorry I have no idea. Could be a manufacturing batch number or sequence number or actually mean they are different parts. One of the online parts fiche can tell you if the part numbers, for the bowls, are the same on both models.

I've soaked float bowls in Berrymans Carb dip overnight and still not had that circuit cleaned. But the guitar strings works every time.
