        Comments about NSI Motor-Works:

        I bought this for my 12 year old son for Christmas and thought it would be exciting since he is always asking me how things work. He had it built but needed my help because it wasn't working... after further investigation the cover for the top was different than the box.. not a big deal since it seemed to not mess with the functionality. but then we looked at the timing belt cover and it didn't have the correct mounting points for the lower half. I then thought maybe we had it spinned a 180 degrees but then it didn't line up either and was not even close. We continued on with the assembly and found that the mount for the drive motor that spins the motor and shows how the pistons move and spark plugs fire was also missing two mounting points. Again it didn't match up to the other side either.
        It seems that we got a defective model. The timing belt will not stay on either (thats if you hold it together and try to run it.)
