My heretofore trusty Honda lawnmower wouldn't start earlier this week.
It's 10 years old and I only use it for trim work. Over the winter, I
run it dry with Sta-bil blue (marine). Unfortunately, I forgot to drain
the carb bowl.

Everything else seemed ok on the Honda motor, so I pulled the carb to
see what was going on. What was going on was heavy duty "white"
corrosion of some sort. Never seen anything like it before. Valleys
etched into the walls of the carb.

So, I took the carb up to a local lawn equipment dealer and the parts
guy said, "That's ethanol 'corrosion' on aluminum...your carb is
ruined." He ordered a new carb and gasket for me, it came in today, I
installed it and the motor started right up.

In the past, I've posted I didn't have any "ethanol problems." Well, I
had a $50 (cost of carb) problem this week.

Next fall, I'll remember to drain the damned carb bowl.

Grrrr.
