Not Iddling on my '04 yz450

Ok, I'm in limbo about this. Do I take it in to a repair shop or have my dad who is a Master Mec. work on it. IDK. So I present this to you, if you can help.

PROBLEM : There is no Iddling with this bike, the knob by the choke will only be totally high rev'd or barely nothing, No comfortable nice idle.

When I ride the bike I either have to me on the gas or grabbing the clutch, to keep from dying...

I have no engine drag when I'm declining down hill or landing, Almost like landing or goin down hill in Neutral, sucks.

Can anyone on TT help me or have any idea whats goin on?

Replace the seal on the needle valve on the carb slide. It is leaking air and can cause that exact problem you have stated!

is this something I can do without knowing anything about Carbs other than the Buns on my double-double?
