Default car problem

I have a xxx-s and it's not working right. The pinion was not on the motor shaft all the way and I fixed it but the problem is still there. It goes really slow and sometimes just doesn't do anything when I give it throttle. The motor also sparks, I dont know if it always did this but inside there's like a row of small sparks when I hit the throttle. if anyone knows what to do in this situation please let me know as quickly as possible.

best suggestion I can tell you is take it to your LHS and have them help you out or get out to a race track and ask someone there to help you...

in the mean time check the drive line for binding, check your motor spacing, even check your motor (maybe there is something inside the can - rock, bolt even a staple)

I would tear down the car and rebuild, carefully checking every aspect of the car as you rebuild.

The motor is supposed to spark a little bit. Have you ever done any maintenance on the motor? If youve run it too long without truing the comm and changing the brushes, that could be the problem.

Your problem with the throttle is probably a hung brush. Take the motor out of the car, and pull on each brush shunt (the wire from the back of each brush). The brush should snap back into place, and it should work after that. If it doesnt, you will need to clean out the motor with motor spray. Your LHS can help you with that.
