Well i finished rejetting my carbs after adding a K&N lunchbox using 150/40.  Right after i did that and put the carbs back together and everything, engine roared to life!  sound was amazing! and i had the idle set way too high, i think it was idling at like 5000 with the choke on.  anyway, after a minute or so, it died.  has not started back up since.  after coming home from class, i noticed a small pile of gas by the centerstand.  i drained gas from carb nipples and tried again, nothing.  is my engine flooded with gas and if so, how do i unflood it?  i'm pretty sure i'm running rich since when it was running, smoke was black, and so were the spark plugs.  almost done with this project, please help!

check float height...  also your floats might be sticking..  try tapping on the carb bowl with a screwdriver.  it would be odd to have BOTH sides sticking at the same time.  did you mess with the floats?

i only took out floats to do some cleaning and change jets and what not.  it did seem as if the float needle didn't want to fit in the hole very well, i don't know.  i will also check to try and see where the gas is coming out of, i was looking around at other posts and some suggested i may have gotten fuel in the crankcase?  fuel drains out of the carbs well.

fuel in the crankcase shouldnt keep it from running.

the float needles drop in.  what did you clean the carbs with? it's possible it screwed up the rubber on the end.. and enlarged it

i believe i used some WD-40 and maybe some kerosene.  i only cleaned the bowls anyway.  i also noticed earlier today that after cleaning bowls and trying out a different setting, i took off the bowls again and they had accumulated dirt in there again, after only like 30 minutes!  it wasn't much, but still ...

also, cheesy, when i first undid my carbs, i accidentally unscrewed the idle screw all the way out, now i have no idea where its suppsoed to be.  i'm pretty sure its running way to rich, how do i make it run leaner?

theres a brass cap on the bottom of the carbs.  you have to carefully drill that out, then set the screw underneath three turns out (from all the way in)

to be honest, i think this whole 3 turns out thing is a bit subjective, i mean, how tight is it supposed to be before i go 3 out?  i am sure this is the problem, with F/A mixture and idle screw and what not, i just don't know where to start turning out from to get 3, i have done everything else perfect according to info all over this site.  also, after the idle screw is turned all the way in, about how much should i turn it out?  thanks again cheesy for the quick replies!

turn it out until the end is barely no longer touching the arm it pushes against.

the 3 turns out thing is very subjective.  mine would get tight, then loose again... so for a little while I had one 3 turns out and the other like 4 turns out because i wasn't tightening it down far enough.



it's more important to have them the same distance out, then decide if it's running lean (taking forever to warm up) or rich (running rough and exhaust that smells a lot like gas) than it is for them to be exactly perfect.

cool, man i will adjust the idle screw right now.  i just checked the float height using clear tube, came up to gasket, pretty cool trick!    i also noticed that it smells like gas in my engine after opening the oil cap at top, oil looks pretty dark too.  i was wondering if there is a way of knowing (sound, smoke, etc) if carbs are either out of sync with one another rather than being in sync but just being too rich or lean.


~Facio

what kind of exhaust do you have?  i just rejetted with 150/140 and 3 turns out.  i have a lunchbox and an aftermarket pipe however.  if you have a stock pipe would 3 turns be right??

i only have a stock pipe, reluctant to shell out the money for an aftermarket one since i'm leaving for europe for 3 months soon ... anyway, i'm pretty sure i've lost count of how many damn turns i've got the thing set at, i am gonna try and fiddle with it now, but it sucks having to ask my ex-girlfriend for rides everywhere ... i hope my new girlfriend starts running soon

turn all the way down and start over.

hey weasel, did u use two #4 washers under the needle jets?  also, how do u know if u have ur carbs in sync and one is not screwed further out or in than the other?

~Facio

i used one washer under each needle.  about the syncing you might want someone else to respond but i'll try.  as far as i know syncing the carbs has to do with teh butterflies.  they should be open the same exact amount.  the screws are mixture screws.  screw them all the way in (not too tight!).  then i unscrewed it 3 complete turns.  im not sure what you mean about turning them both the same amount.  i dont see how that is a problem considering you are looking at teh screw as you turn it.
