The last engine I took apart had little ridges built up around the circlip 
groove.  I couldn't get these pins out either.  I made a tool to pull the 
pin out.  It consited of a 3/8" bolt and a 2 washers.  One washer was cut to 
make a "C" shape, while the other is normal.  You just slip the bolt through 
the pin and then slip on the C washer.  By tightning a nut on the bolt,  the 
pin will be pulled out.  Once the pin has reached the outside of the piston, 
You have to put a socket on the bolt and start tightning again.  
        The only other thing I had to do is file slightly on the bolt's head 
(at the points) so it would slip through the pin.  The bolt had a 9/16"head. 
 It is best to use a bolt with threads the whole length, as you could put 
the socket on first, and pull the pin in one fell swoop.
        After the pin was out I noticed that the little ridge had been cut 
right out of the pistons.  H very sharp piece of aluminum, so be carefull.
  
Good luck.
