Actually it's not that "gross a hack". The support arm is mounted with 4 large bolts to the motor mounting plate. Inserting a shim between the arm and the plate will let you adjust the wheel's distance from the motor. It's not fast, but it's precise. I've loaded a photo of this section on my website: http://www.generalist.org/madmike/sparrow/SparrowMotor1.jpg Be forewarned, the photo file is 593kb in size. The motor is in the rear, small sprocket is hidden inside the housing on the left. The support arm attachment is in the center and the large sprocket and tire are on the right. I will create a smaller version of the file Tuesday by noon (US eastern time). It will be called http://www.generalist.org/madmike/sparrow/SparrowMotor1small.jpg I am replacing the belt on this sparrow later this week. When ordering, they mentioned that some of the new belts are a slightly larger diameter. The new belt came from Corbin with thin shims. I still need to talk to the Corbin rep about the exact installation of the shims. I'll take pictures if I can. -- Michael Shipway [EMAIL PROTECTED]
