I don't know what formula you might have, but I would like to offer a word of advice on technique. After you apply the penetrant, give the screws a smart rap or two, to break the mechanical "lock", then wait awhile to let the penetrant get into the joint. Don't break or bend the screw, just shake it up a bit. This helps. As to a penetrating oil, I've been using "Nut-Z-Lube", available from one of the list members in Canada. Joe Savard, Lake Orion, Mi.

I have screws in some carbs that are VERY hard to loosen. Does any one have it and can send it again as I am probably not the only one that could use this info.
