Today, after reading up on couchdb I decided to take a break from vapour-ware and high-flying ideas and Do Something Practical, like finally take apart my whipper snipper to figure out why it doesn't start (different kinds of vapours are involved, this being a cheap two-stroke FPOS).
Enthusiastic tool application quickly demonstrated one big issue with any metal FPOS (remember, I said cheap): very rough edges. Slipping and sliding the back of your finger along such edges is highly counter-indicated.
Well, there must have been a caterpillar lurking beneath the skin on my index finger, because this not-so-deep cut was dribbling red juice beyond what I'd have expected; and the motor oil, petrol and other assorted grease-suspended gunk on my hands didn't exactly make my journey to the bathroom any cleaner.
But the icing on the cake came later: I did, of course, finish the disassembly after wrapping up my finger - only to find out that the whipper snipper engine is beyond salvation. Just about zero compression, most rubber/plastic parts rotten. A new one will likely cost less than the replacement parts, never mind the time and effort for a potential repair.
