    on this the speed of the motor is critical to making it work(less speed = less kick to the ball making it launch forward). try changing the batteries in it.

    You should try taking out the two outside(the ones in between the top and bottom) gears. I haven't made it myself, but it looks like it would still work. (P.S. you would also have to take out some of the chainlinks)
