Subject: Re: Europa-List: Water corrosion?
After a lot of running problems I have recently stripped the carbs and found
the bowls to contain a considerable quantity of a white substance - almost
like that deposited by hard water, but much more powdery and soft. The
aircraft has not been flown for some months while under maintenance. I have
cleaned out the bowls and jets (slow running jets completely blocked) and found
no
corrosion, but no-one appears to be able to help in suggesting where the
white powdery substance came from in the first place. The engine has been
run
on mogas only for the last year.
Any responses and suggestions of cause and future preventitive measures will
be welcomed.

---> White powder is typically aluminum corrosion. It isn't from the gas
itself,
but merely a product of whatever in the gas is eating the aluminum.
I'm guessing that you've got some water in the gas that is settling out in the
fuel filter (where it should be collecting) and the carb bowls (where it
shouldn't
be). The water is then corroding the aluminum.
Question, have you checked your mogas supply for alcohol content?
