I start my engine in break in (i messed around with the needles)
and it idles for a few seconds then rev's like im giving it gas but im not so i give it break and it stalls!!
What do i do?

Set the needles back to factory spec. More than likely your low-speed needle is set too lean, give it a half a turn counter-clockwise to richen it and see if that helps.

Ok thank you... i don't know what factory setting are though :\ Grp .21
this site says http://www.horizonhobby.com/Articles...ArticleID=1897 0.045 but i don't know if it's inch of centimeters or milimeters

nope it didn't work...
It sounds like when you are running low on fuel and it revs high!
Any ideas???
Im going to try to richen it up more...
but what could be wrong?

Turn the LSN and HSN 1 turn out (richer). Start it up, if it doesnt start lean the LSN 1/8 of a turn. Do this until it starts. Also blip the throttle very fast when you are trying to get it to start, it helps alot. Did you heat the engine up? Once it starts, richen the LSN 1/8 of a turn and start leaning the HSN a bit until the idle is slow and consistent. Might want to also adjust your idle. I just like to mess with the needles a bit.

Also make sure your throttle trim on the transmitter isn't turned up all the way. If you richen the needles (turn counter-clockwise) 1 full turn as Chris stated and it doesn't help, then you've got an air leak that's shown up somewhere. There should be three adjustment screws, High speed needle on top of the carb, Low speed needle on the side of the carb, and idle speed normally on the front of the carb.

I figured it out!!!
I got it to run but once it ran for like 5 minutes i would encounter the problem it was like a 1/4 throttle run away that i could steer but not stop... and if i braked it would not stop it because the break i adjusted them really weak.
It's probably and air leak right??? because after i shut it down i heard a hissing noise. It sounded similar to wind blowing on a fire. that is probably hot air leaking out right??
If so how do i fix it?
