Unidentified Carb part (550 CV carbs)

[Guest]

Ok, so about a year ago, I re-built my 550 carbs to be put on the 650 using a k&l carb rebuild kit. They have been working great, but now it is time to reclaim the 550 carbs for the 550 (see my thread in appearance mods).

Anyway, I pulled out my marked baggies of the 550 carb bits and as I was looking at them I noticed this little piece:





I see no mention of it in the carb rebuild series, and I seriously forget if it came out of my 550 carbs, or was just a piece that came in the kits that I didn't use. Anyone can tell me if this is actually a part that belongs in there somewhere, and if so, where.

Looks like the infamous cap for the idle air screws that befuddles everyone and has to be drilled out.

Does that hole go all the way through?

Another possibility is the plug that goes between the float bowl edge and the bottom of the throat, but that one does not have a hole through it. This plug does not usually come out, and there is usually a square-section o-ring between it and the float bowl gasket that holds it in place.

Yes, the hole does go the whole way through it.

I just put the carbs back together for the 650 and I don't know where that little piece would go.

The best place to put them would be in your aluminum recycling bin.

Once they have been removed to properly set the mixture screws, they are really of no further value.

Ok, just wanted to make sure it wasn't some slight change that the 550's carbs had that the 650+ carbs didn't.

Here's a pic of the caps that came with the new idle air screws I got a few weeks ago, along with my cell phone for a little scale. As stated there's really no use for them.

Sweet.. I guess I'll put them in with the scrap metal and get my $.000001 for them..

Prices must have gone up.
