Ethanol has already destroyed (as in embrittled, causing chunks to break out) the fuel lines on my weed trimmer

Just had my snowblower in for repair. That Ethanol was a big part of my $163 repair bill!

Drain all fuel out of your small engines when you put them away for the summer/winter. This includes running them until they stall out and lastly drain the bowl of the carburator. This is the only way I have learned(the hard way).
I replaced one carburator on my hedge trimmer. I have also replaced fuel lines on my lawn mower and rebuilt the engine on my lawn tractor.
Lastly , I blew the engine on my Toro 2 stoke snow blower.
I blame ALL of these problems on Ethanol in the fuel.

ALSO, DO NOT TO FORGET TO PUT MOTH BALLS IN A STOCKING ON YOUR ENGINE BLOCK TO KEEP THE MICE FROM NESTING IN AND AROUND THE ENGINE AND AIR INTAKES.
