I don't know what the problem is do you

So I bought this bike with 1008 miles on it recently so obviously it had sat awhile once I got it home I figure I needed to clean carbs so I ordered carb kits for both carbs put them back together had gas leaking from one float seal pulled it apart seal wasn't seated correctly so got it back together thought I had it figured out nope now fuel coming out of the tank vent hose and what looks to be about the float bowls on one carb ... what is this please help.... is it vaccuum  problems ....

RIGHT, there are a few things this could be, but let me just find what I said last time someone asked this sort of question (I fought with the same thing)

1. Incorrect float height, allows gas to always flow into carbs bad news. Link to help with adjusting float height (there's also some info in the wiki):

2. Bad float needle (or, as I like to call it, silver-thing-with-rubber-tip-connected-to-the-float).  Just look at it. If it looks buggered (worn, cracked, etc) it needs to be replaced.

3. Bad float valve o ring (brass colored thinger that the needle rises into has this one) you can test this bit by constructing some manner of contraption to hold the needle in there firmly, or just cover the holes on that brass bit with your fingers and pour some gas in the correct tube. If you have a helper I advise the 2nd option. If not you need to grow another hand.

You can also just pull the valve and look at the o ring, this is the bit that was causing me issues and it was comically bad.

Hope this helps and sorry if I seem like I'm talking down at you, I simplified it to the point at which I would've needed the info when I had a similar issue.

No your aren't talking down to me I'm glad someone could shed some light for me I jut replaced float needle seats when I cleaned carb old ones were dry I may not have got them in all the way.... would this cause fuel to come out airbox vent tank vent and what looks to be the upper end of the carbs

[mennobike]

if they didn't seat correctly, yes.  Try seating them well (some members a bit of oil or gas to get them to slip in and seat). Hope you get it worked out!

Awesome will do then I'll let you know thanks

ok so no more leaking fuel but i have hanging throttle when i try to adjust idle screw it moves a little then goes down to about 800 and dies

[mennobike]

did you replace all the o-rings in the carbies or not? There's one that the floats seat with (a small one) that effected my throttle, but I'm not a hanging throttle expert, either
