The yoke is a pretty big part to try and do any good with just a propane torch. Glad you were able to get it loose. Any type of penetrating oil takes much more than just a few minutes to work. When I'm planning to work on something rusty, I start early in the week. Walk by it on Monday with a can of PB Blaster, shoot anything that looks like it might be frozen and go to the office. Spray them again on Tuesday and maybe Thursday. By the time I get around to it on Saturday or Sunday, shoot them again and everything usually comes apart without too much trouble.
There are exceptions, such as those confounded radiator carriage bolts. I just expect those to be stuck and spinning in the thin radiator sheet metal. In cases like that a nut splitter or reciprocating saw will probably be the next tool I grab. Sometimes good used parts are so cheap it makes no sense to fight the rotten stuff.
After spraying penetrating oil I'm a bit shy about using a torch of any kind. Burning and sniffing those fumes can be really bad.
