Zenith Tricks of the Trade

Are there any fool proof (referring to myself) methods for extracting the Adjusting Needle Housing from Zenith castings? I've got a couple of these that just won't come loose with a wrench.
I've tried penetrating oil, lots of bad words and searched for 13/32 wrenches to no avail. I have experience with being irrationally exuberant with those brass fittings and would like to avoid those results this time.
Any sage words of advice would be muchly appreciated.
 
Deep 6 point socket. Now 13/32 ( .406") may be hard to find, but try a 10 mm socket, pretty close, should fit.

Soak it in Kroil for a few days. Get a helper to help you gently secure it in a vice. Don't bust it, or scar up the mating surfaces. Turn the sir down on an impact gun, and use the 10MM deepwell with extension(s) that will let you rig that little socket up to your 1/2 drive gun. 20 lbs ant first. Then bump the air up 5 lbs at a time. Remember, patience is your friend. Once it turns one quarter you are likely home free.
 
Heat it up,put a dab of Lard on it. Will come right out then. This works every time on Marvel carbs also.
 
Wick, I have seen that done with an accetalyne torch and bees wax on exhaust manifold studs that are broke off and rusty. Of course you would melt a carb is you used that kind of heat.
