I tried it on an old 2-barrel carb from my '72 F100 that's been sitting for years. After three 8 minute cycles with some simple green and water, the jets were actually clean enough to see through. Has anyone else had luck with these things for small engine parts?
I was stuck on a seized brake caliper bolt this weekend, soaking it in PB Blaster for 20 minutes with no luck. Then I remembered a short clip where a mechanic heated the bolt area for 30 seconds and it twisted right off, so I tried it with my wife's hair dryer and it actually worked. Has anyone else had good results using heat on stubborn fasteners around the garage?
