Sounds like you broke the steering servo.
Move the tires by hand. You should be able to hear the servo moving. If it is broke you will feel it moving too freely.
Hard to say what is wrong with your motor.
Put a new glow plug in to start. Then....
Take the manual and go thru the set up proceedure again to make sure you have the carb settings correct. It is supposed to leave a small trail of smoke when you are hard on the throttle, but not all the time. Chances are it is running way to rich. Too much fuel.
Hope this gets you started in the right direction.
