It's funny, my dad has a 262 slant six in one of his trucks..  asked me to
do a tune on the carb.  I have no friggin clue how to do that.  Yet i've
done all kinds of EFI stuff, gone as far as making my own crank triggers by
modifying junkyard parts, etc etc.   yet...  i couldn't tell you how to tune
a carbeurator.  It's quite interesting.  I guess i'm just part of that 'new
generation'  that understands fuel injection as a whole, but all that
'analogue' technology still baffles me.

I'd be the one who'd actually build and use the 555 timer IC type fuel
injection on my weedwhacker before i'd actually figure out how to fix the
stupid carbeurator on it.
