which one is the float needle?

Needle and seat assembly is No.33 and O ring is 34.

[Garrett]

They're out of stock. Crap.

[ben2go]

Also use this write up to check your floats to see if they need to be adjusted. http://gstwin.com/float_height_check.htm

The fuel level should be checked on a level surface with the bike on the center stand.The fuel level should be set at the split between the carb body and carb bowl.Bending the little brass tab on the float raises or lowers the fuel level.bending the tab up,lowers the fuel level and bending the tab down, raises the fuel level.

They're out of stock. Crap.

This place is higher but usually in stock.Still way cheaper than the dealer. http://www.oldbikebarn.com/Suzuki-GS500-GSX1000-Carb-Repair-Kit?sc=12&category=73881

Ordered.

I've got a new petcock and carb rebuild kit (float needles and gaskets basically) coming this week. If it doesn't fix it then it's going to the shop.

[ben2go]

If you were in my area,I'd lend you a hand fixing the issue.

[NickyNumbers]

your getting more out of this than you think though, after this you'll know this bike in and out. Its frustrating, but its a great learning experience. 



I had similar problems with my GS for a week or two.  When I rebuilt the carbs, which I had never done before, i discovered both float needles were completely siezed and I had symptons like your describing.  Get the carbs off, buy the Clymer manual and be patient with it.  Make sure the float is within spec by doing the hanging test, make sure the needle is set correctly.  Check the bottom of the float chamber for rust.  Check to make sure the little o-ring is on top of the diaphram.  Check that the main jet has an o-ring as well.  All the little things count on the carbs, the devil is in the details.   

Once that is all clicking, get it back on the bike.  Make sure to reset the mixture screws on the bottom and then turn it out 2 turns out.  Fine tune and adjust from there.   

Carbs are not a set science at all, it takes some practice and eventually you'll know what your bike likes.

Here is the tuning procedure for our type of carbs.It explains how each part effects the running of the engine.

[Garrett]

Do you happen to have a pic of the mixture screw? I did not adjust it when I jetted them.

[ben2go]

Just for you my friend.

[Garrett]

So I "tighten" them, then back them out the required number of turns? thank you so much sir.

[The Buddha]

Just snug, not tight. Lightly seated then out 3 turns.
Cool.

[Garrett]

Awesome guys, thanks for bearing with such a noob and answering all my dumb questions

[ben2go]

You're welcome.

[Garrett]

I pulled the tank and air filter off and noticed the carb as not seated all the way  :icon_eek:and started it up. It ran smoother than before but everytime I gave it throttle drops of fuel were being shot out the carbs  Is that normal?

[The Buddha]

Shot out of where ? no its not normal.
Cool.
Buddha.

[Garrett]

it shot out of the cab toward the air filter  It wasn't a lot but it was a noticable amount.

Also, one of my mixture screws is fubared. It won't turn and the screw top itself is all broken

[Garrett]

I pulled the top part, diaphram I think, off and number 5 on both sides was just laying inside number 9:



Where does number 5 go?

[ben2go]

#5 goes on top of the needle and clip that is in #9.It sounds like you need to buy another set of carbs and use yours for spare parts.I'll post a pic since you haven't seen my carb write up. http://gstwins.com/gsboard/index.php?topic=56601.0
