Thanks for all that. This is my first car and i only have one plug (which already came with it) so i had to take the plug everytime to check if it did work or not.

Like two hours ago, it finally worked. I still dont know why, i just messed with the needle and it started. I let it idle for the first tank. Then on the second tank i let it idel till the hafl, and then i started playing around with it, i pushed the trigger like 1/3 and it was barely moving.

Now the thing is, the engine is revving alot when it finally starts moving. Is it normal? I have to push the trigger like 1/3, the minimum aperture of the crb is like 1m, the maximum is all opened, the servo linkage is fine... There's another little needle taht i cannot reach due to the fuel tank.. what does that do? it doenst even come on the manual, but GALAXY on the other post said that the nitro star 12r ss(which is my engine) had another needle, so i found another small screw and im thinking that's what he meant.
