I posted the following:
"Jared, It's months later, so you probably already figured it out. But if not, try this:
The conrod and wristpin are probably stuck together with gummed castor. Wrap it in a rag and gently clamp it upside down in a vice. Fill the inside of the piston with wd40 and let it sit for a while. Take an allen key and use it to try and pull the rod loose. Work it back and forth. If it won't come, use a heat gun and keep trying, and it'll finally loosen up and slide off.

Better yet, type this into google:
"super tigre wrist pin stuck site:stunthanger.com"

Here is the list of results I got from doing that:

Some times the pin will not come out. Several have written this up before so I am not taking credit for it.

Do not remove the sleeve completely. Move it high enough so the pin will clear it. Drill a hole in the front of the case opposite the exit hole on the back of the case and use a drift punch and drive the pin out. There is no need to fill the drilled hole as it will not leak. I saw this on a ST/46 back in the 1970's when rebuilding a motor. I thought about it for a few minutes and realized what the hole was for. Good idea that I use a few times over the years.

I will look and see if I have a drilled case and take a picture of it.

So IT WAS YOU thats been at one of my . 46's !  ( anyone want a cheap 21/46 ?  :()

Ive found with engines stored from the Jurasic Period , periodically boiling And C R C ing them , say four times over a fortnite MINIMUM
and ' a positive disposition ' afterward , they will disassemble ( almost ) unharmed IF YOUR CAREFULL .

A Leather Strap on a stick to rotate a iron fin sleeve possably safest . The Easy Outs should pull a gudgeon , after the GUNK set has been SOFTENED ,
Rotateing it first. Carefully . Like You Say , the liner bottom just over the pin , will suport the piston , whilst you do your worst . Being Carefull of the ring .

The HEAT CYCLES seem to be the trick , for the penetration of whatever , and TIME to soften whatevered baked / solidified Castor Oil .  :(

The Query was just as one of these Californians seemed stuck (  :## ) for a cure . ( not ME on U Tube ) .

Best pulling the Gugeon / Wrist pin - but usually ?? Ridges of ' coked castor ' & or Corrosion on the pin makes it awkward to start moving . Thanks for the hits . ;D

Think its a bit excessive drilling it , personally , But you can Helicoil a V W Bug head by cutting a flap in the inner fender , after removing a wheel , if you havnt time to pull the engine .  VD~
