I have a McCoy Redhead 35 that was frozen with Castor oil. I have freed everything up except the wristpin & connecting rod. I have tried a little heat with no luck. It has soaked in carb cleaner(out of the spray can, Autozone) for two days, with no luck.
What should I try next?

Even more heat is the answer. Assuming it is problem with stuck castor "adhesive" Get it really hot and bothered with heat gun. I have never known this fail but......If it does put it in the domestic oven and turn up the wick!
I used my wife's hairdryer yesterday and unstuck a diesel wrist pin that was very stubborn.

Put the motor in Crock Pot with antifreeze overnight on high. It will be like a new motor in the morning.

If you go the crockpot way be sure and take the head off or you will have to repaint it as the crockpot antifreeze will remove the paint. I have not tried it, but someone said that you can heat the rod wristpin with a soldering gun. That should work.
