[Coco] looking for joystick repair tips.

[William Schaub]

I have two deluxe joysticks that seem to need my attention. they don't 
register the full range of motion particularly on the down and up 
positions. I was wondering if anyone could give me some tips for 
restoring coco joysticks. (the ones in the white case that can be 
switched from spring loaded to totally free and have calibration levers)

I know I will have to take it apart but I have no idea what I am looking 
for. is it just a simple matter of cleaning or are there some components 
I will have to replace?
