The manual with my generator goes thru how to prep the unit
for storage. One item is to loosen a screw under the carb,
pull plug wire, and crank it to force out the remaining fuel
in the lines and carb. (all this after emptying the fuel tank).

My question is: what is wrong with just letting the beast
run out of fuel and stop? They don't mention that
possibility in the manual. Thanks for opinions (and surely
some flames from the shutins).
