Bing question, 64/32/2

I have some R80 carbs that I am going through and I have hit a road block, Im hoping someone here can point me in the right direction. I am installing the float needles and i cant remember the orientation of the wire clips that go on the float needles. Sorry I dont have any pics, my Smug Mug is giving me problems.

BING shows it as the straight part through the needle, maybe: http://www.bingcarburetor.com/pdf/MO...DED%20VIEW.pdf

Thanks, didnt even think that the diagram would be any help. I wasted an hour surfing the net looking at Bing images. My next question is ;
Does the straight part of the wire go under the float pin or over it?

Xtra credit question

Can i use a little grease in the groove that the diaphram sits in to hold the diaphram in place while I put the top on? Thanks......

The clip should wrap around the floats tab, WAY easier to hang them off the floats and install when the carb is upside down and off the bike... Shouldn't need the grease. doesn't it just sit in the groove? Make sure the tab on the diaphragm is centered in the notch.

+1 on all counts.

The diaphragms won't rotate if you are careful.

I was having a hard time with one of the diaphrams, I think it is an aftermarket one. I am ordering a new one as the other just is too small. The diaphram on the other side fit perfect..i figure out the trick with the clip, thank you for all the help.

There's another trick with the wire clip.
Throw them in the bin.

I was wondering if you could get by without the clip. Dont they account for a space between the tang and needle?

Nup.

They pull the needle down from the seat if they become lightly stuck from sitting too long, or if wear on a rubber tip type needle helps it to 'jam' in the seat.
The needle won't fall out without it.
81 RS carbs anyhow.

Just had the needle and float out of one a mine. That clip doesn't appear to interfere with anything. I probably put the 'latch' on the bottom though.

Here's a picture of how not to do it .... but it's a little less fiddly to install the floats this way. As you can see the wire clip is holding the needle in a vertical position while you offer up the float and once installed the clip can be maneuvered into a more correct position. Note I said a little less fiddly, it's still a pain lying on the garage floor with the carbs on the bike.

These carbs will usually work fine without the clip. Only sometimes or once in a while will the needle get stuck so it's good to have the clip there.

So once it is installed, where does the clip end up? Does the float pin go through the loop in the clip? I missed this part during the disassembly.

The float clip ends up loosely hooked over the tab with the straight part on the top and the open part underneath. Starting from the position above push the clip towards the back of the picture and spring the curled bit over the back edge. The clip will now hang loose with no tension on the needle pin.

To tell the truth it's a million times easier with the carbs upside down on the bench. The only time I attempt to fit them with the carbs mounted is when I don't want to disturb a known good carb balance.
