Loosening Off Seized Screws

Some screws, you just have to look at them to know that they're likely to be seized in their threads; e.g. those two 1/4" - 20 screws holding the muffler on a Tecumseh lawn mower engine.

Don't go directly to trying to unscrew them. Instead, try to first tighten them a tiny bit. If you can get a seized screw to budge at all in the tightening direction, you're much more likely to get the screw out without breaking it, like so.
