Chainsaw Repair

One needs gas (but not with too much ethanol, please. Or stuff that is too old, thank you); floods; requires repetitive, rapid jerking on a starter rope, choking and purging while it is held in your crotch, or thrown/drop started; needs periodic spark plug gapping and maintenance, air cleaner cleaning, tune ups, and maybe points adjustments; need carb adjustments when you change altitude, or the temperature drops; puts out toxic CO smoke; is a fire hazard in your house; is too loud to hear co-workers over; gets hot and shoots sparks that can start forest fires; leads to vibration related nerve damage and hearing loss; can be lean seized or straight gassed; and has led to the creation of a large library of curse words.

The other starts when you squeeze the trigger.  And stops when you release it.
