Clutch Master Cylinder Piston

["Cary Henry" <caryhenry@hotmail.com>]

How in the heck do you remove the piston from the clutch master cylinder.  I 
was able to punch the piston out of the slave cylinder, but I can't get a 
piece of rod into the master cylinder due to the angle.  I tried compressed 
air, but it blows the reservoir cap off before blowing out the piston.  Any 
Ideas???
