ok, once again, Im sorry about starting yet another thread.. I promise once I get over my carb cleaning fears I wont post as many threads for one thing... I don't like to tie all my post together as I said before. Im just wondering what I do tomorrow with the float and needle? I believe that's what I call it. im taking carbs out of motor, open them up, I take out the fuel screw(by counting turns) take out main jet and pilot jet, clean all that stuff real good, but then what do I do with the float? i know i asked this before but im still confused. I read on another thread that i just pull the pin out of the float and it lifts up?? is it one pin? how does this pin come out? once i pull the pin out, does the float come off by itself or is it attached to more parts that need to come off? im afraid to mess with this float and bend it as im not skilled enough to make adjustments to it, but i also want to make sure it is cleaned and good to go.. If anyone would be so kind to walk me thru the float cleaning process i would appreciate it. i am attempting this tomorrow morning.. also is it ok to take all the parts out first then clean it all at once, meaning all the jets and fuel screw then clean them put them all back in?? thanks for the help, and believe me, if i can do this tomorrow with no trouble i will be posting that tomorrow night on this site..thanks again

The last 3-4 pics show clearly the "pin" your talking about.It is press fit into the tangs/tabs/posts what ever you want to call them. One end of pin has a lip, obvious which way it needs to go. To head your next thread off at the pass, yes these can be a pain in the *** to get out. Once pin is out the float/arms assembley is free to lift out. Your needle valve will be hanging by a little wire clip and should come with the float assembly. With that out of the way theres a phillips head screw holding the seat in place. Seat is brass tube looking deal the needle fits in side of. Remove screw, remove seat (you have to grab with needle nose pliers) Should be a concave screen cap thats "snaps" over the end of seat. Remove screen. Clean all parts with carb clean then put it all back together the way you found it with out the crud,chalky residue etc.
 
One of the best tools I purchased to get these Yamaha float pins out was a spring loaded center punch tool( you can pick them up at Home Depot or Lowe's or probably any decent hardware store). It really works great at popping the pins out. Like Devil said, they are a pain in the a** to remove. Very tight fit! If you go trying to pound it out with something you stand a good chance of snapping one of the posts that the pin slides through. If that happens.........
not good. With the punch tool all you do is push it against the end of the pin, and push until the spring pops and out comes the pin. It will go flying out so be careful. On my punch I can unscrew the end a little and it softens how much force the spring pops with. Push down on a piece of wood so you understand how it works. In my opinion it's well worth the 8-9 dollars.
Follow the pictures on the site and what Devil told you to do and you'll be fine. Gotta commend you on taking on the carb clean. It's really not that difficult just take your time.
Before you take out the fuel screws, screw them in (counting the turns) until they LIGHTLY seat. Then you know where to put them when re-assembling.
Good luck

As well as I know at least one member PMed you his cell number. He can explain step by step over the phone being very detailed rather then a ten page response.
 
When I clean carbs I don't mess with the needle and float. I take out the mains, pilots, and fuel screws is it. Hasn't failed me yet. Just my $.02.

The only time I touch the needle is when I'm rejetting for altitude and/or temp change.
 
if you havnt allready read through the tech help for carb cleaning. gives barney level instructions for everything.
