Vacuum motor problem today. I was having a problem with one of the motors not working. I opened the top and tapped the motor and it started working again. But the motor started sparking. So I just replaced the motor. I am not really sure if I could still use the sparking motor though.
I was surprised how easy it looked to fix the blacktop today. Just dig out the problem area. Then heat up the problem area, add black stuff in the hole then heat up the black stuff. Then use a flat metal rack thing to smooth it out. Then use the shaker thing. Done. It is that easy.
