The oddball 83 GS550 carb

[robertbarr]

I'm trying to help a new person here with a pair of these 'two-barrel' carbs. I've found that a few of the O-rings from the 'normal' CV's will fit, and they cross-reference OK, using the exploded diagrams on Flatout (and elsewhere).

The question is -- these exploded diagrams are not complete. They don't show any type of mixture screw, and I know there must be one (per carb). I recall a few people have hashed through this business with the O-ring quandry. How did it turn out?

... or, does anyone have a link to an actual complete exploded diagram, showing a mixture screw?

I'd like to get this information down pat once and for all.

Each carb has two idle mixture screws.

550 screw and oring are on left, BS (from GS700) are on right. They are identical orings.

That's exactly what I needed to know. Thanks a bunch!

Happy to help!:-D
