I can just picture a black widow under the motor shell...
I'm always nervous when tearing into an old machine that was stored in a shed, attic, garage or barn. I have an irrational fear of black widow spiders. Luckily I haven't come across any even though a few vacs I've taken were just covered in webs.
I've been an HVACR tech for almost eight years now and the absolute worst part of the job out of anything in my opinion (even compressor terminal blowouts!) is encountering a black widow, especially in confined spaces. Doesn't happen too often but you'll go into a crawlspace, attic or whatever and there they are. Day ruined, lol
