re: Fuel going off.

Adding a fuel stabiliser should eliminate the problem, eg, http://www.briggsandstratton.com/eu/en/support/vid...

Alternatively, "draining" the fuel from machinery isn't a big deal,

Don't fill the machine right up near the end of the season, just use what you need to.
When finished, leave the machine running until it runs out of fuel.
Done.

You could debate for years the pros and cons of either approach.
