where does this part go

[Guest]

I am doing my carbs on my gs850 and using the carb cleaning guide but I don't see where this small screen goes .I am trying to attach a picture. 1466185788735.jpg

Could be a filter from needle jet valve, the main fuel in to float bowl. Other part looks like a pilot jet.

Can't tell from that angle, is if flat or dome-shaped?

The brass part is the pilot jet and the black rubber part is used to hold the metal plug in place but I'm not sure that's the picture you intended since there is no metal screen shown.

If the screen is domed shaped then it goes on the bottom of the float valve seat. If it's flat then the screen is still associated to the float valve, but it's an after market float valve seat.

Please get more acquainted with the site. A simple review of the carb rebuild tutorial would answer your simple question.
If you can't even identify 2 common carb parts, how are you going to bench sync, set float heights, and even rebuild the carbs?
The carb rebuild walks you through the entire procedure.
Pictures, descriptions etc.
No shortcuts. Do a thouroughly and proper job aND the benefits will be numerous.
A GS that pulls hard and cruises smoothly as glass is amazing. One that takes forever to start or stutters under acceleration is a real let down.

TRUTH ! I know first hand when my 850 ran well it was a real wonder -- now that it stutters and runs poorly it is miserable (carbs soon to be rebuilt)

I just put the pilot jet in for size reference, I know what it is and I have redone these carbs before with good result.
There is no picture in the tutorial for this part so that is why I asked. I was several months ago that I took them apart and was waiting for a new carb body which I have now. This is the pic I intended and the part is not rubber but hard plastic. The center of it is very fine screen or mesh. It is flat.
I am familiar with the site and the vast knowledge base here, that is why I asked.
Thanks for the feedback.

It's a float valve seat inlet screen from an aftermarket float valve. In many cases they just fall off. Not absolutely needed if the screen on the petcock is in good shape, but you might want to consider replacing the float valve assembly anyway. The reason you don't see it in the tutorial is because it's not a replacement part. It's considered part of the float valve assembly.

I cleaned the tank and installed anew petcock so probably not needed at this point. Thanks for the starlight up definitive answer.

[stickid]

Actually that makes perfect sense now because I did replace the float valve when I redid the carbs before and did not see this part so it must have been on the float valves and fell off when I disassembled this time.
One of life's little mysteries solved.
Thanks

Just one more example of why aftermarket carb parts suck. The OEM screens almost never fall off.

[stickid]

They are back together. The screens clipped right on firmly so all good.Now to gang them together and install. Hopefully have it running tomorrow or the next day.

That black ring with a screen goes under the float seat on a particular type of aftermarket float seat which has a differently shaped round stanchion for pressing it on than does the genuine Mikuni float seat. The Mikuni float seat uses a dome shaped brown or yellowish plastic affair to filter fuel going through the seat and stays in place much better than that flat screen you have in the picture.
