Ok i done everything u said, in the picture.

Still revving up. The fuel tank was'nt broken, it just was'nt sitting right on the holder and thats the fuel tank from my other savage which work's perfect. The throttle linkage is like that to make sure the carb is at mm open, and plus iw as changeing a servo at the time and their is a throttle return spring. I really have not got a clue whats going on here. I'm not gonna let it rev out of control as that will ruin the engine.
