ok so i took off the top of the carb and peeled the rubber dealy off and pulled out the needle and the clip was what looked to be the 3rd or 4th notch down... so i put it all the way up to the top.. and now it runs like **** idle and if i try to give it throttle it dies... is this because its not getting gas now...

if figured instead of going up one or whatever i would start at the top...

is that what that means is its not getting any gas now?

im gonna move it down one notch and see what happens..

 

The jet needle and needle jet affects carburetion
from 1/4 thru 3/4 throttle. The jet needle is a long
tapered rod that controls how much fuel can be drawn
into the carburetor venturi. The thinner the taper, the
richer the mixture. The thicker the taper, the leaner
the mixture since the thicker taper will not allow as much fuel into the venturi as a leaner one. The tapers
are designed very precisely to give different mixtures
at different throttle openings. Jet needles have
grooves cut into the top. A clip goes into one of these
grooves and holds it from falling or moving from the
slide. The clip position can be changed to make an
engine run richer or leaner. If the engine needs
to run leaner, the clip would be moved higher. This
will drop the needle farther down into the needle jet
and cause less fuel to flow past it. If the clip is lowered,
the jet needle is raised and the mixture will be
richer.
The clip position changes the air/fuel mixture
on the jet needle.
The needle jet is where the jet needle slides
into. Depending on the inside diameter of the needle
jet, it will affect the jet needle. The needle jet and jet
needle work together to control the fuel flow between
the 1/8 thru 3/4 range. Most of the tuning for this
range is done to the jet needle, and not the needle jet.

 

you should move the needle clip 1 notch at a time to try to improve running. chances are on 4 stroke wheelers w/ everything still stock, you shouldnt have to move the needle clip at all. imo.

 

ok well figured it out.. runs pretty good .. best yet .. when i first moved the clip dealy that spacer that goes between the spring and jet needle... well i had that at the bottom and the jet needle on top of it so it wasnt doing or creating the vaccum.. so i figured that out n put it back the way it was and all is good.. it has alotta bottom end.. it didnt have that before so we'll see how it goes

 

Can I ask why you where moving the clip in the first place. If you didn't install exhaust or a k&n air filter you shouldn't have to move the clip on the needle unless you find it too rich or too lean.

 

yea it was too rich u can smell the fuel in the exhaust.. i wanted to lean it out a little... seemed to get a little more power after i moved it up 1 notch..

 

plug color is the important thing look for a cinnamon color after runnig the engine for a while and killing it under load and checking color

 

i just adjusted my needle cause my K&N was make n it lean. If i check the spark plug after riding i can see if it was a good move or not?
