Hey my 150cc dirt bike carb is having idling issues PLZ HELP!!?

I can see that the jet needle was bent a little bit when i got the bike so i bend it back to the 90 degree so it would more likely fit in the carburetor. i probably need a new jet needle because my guess is that its hitting the side of that hole and then falls down. It usually starts with a good idle and then it grows until it sounds full throttle. i cant find the exact brand of the carburetor so should i try to find a jet needle that will work i mean are these things pretty universal or should i just get a whole new carburetor.
