Carbs Ethanol mix

Just one of many I have seen. Even got me once on my Gen carb.
Only E-free in it now for storage.
Stihl 034 carb that set with ethanol mix in it year after year.
Can tell it got some moisture in the tank over the years and was
never dumped.
I've had them come in so bad the gel clogged my strainer to
check their mix in a clear jar.

Some info to save by Bob aka spike60
It's definitely the ethanol. Some of the variables being
discussed here are due to the fact that all fuel lines are not
the same as far as the material being used. Since 2006 most
Husky/Jonsered fuel lines were reformulated by using what i
think was called "hydrogenated nitril" to make them more
resistant to the effects of ethanol. At the time, this was
mostly the curly "pig tail" line that was used in most 300
series saws, and still used in the 372's and 455/460 ranchers.
They have since moved to model specific molded fuel lines for
the 440 and 450 chassis and all of the 500 series saws and I
can't remember that I've ever seen an ethanol failure with these
newer lines. Not really sure what they are made of, but
obviously improved.
The clear line used on the Poulan stuff is horrible, and prone
to exactly wat was described in the opening post. Dry, almost
turns to powder inside the tank. (It's clear when installed, but
never stays that way.) The Poulan based 136/141 saws which I
really hate to see come in, mostly have the same issue: Fuel
line rotted and broken off right where it comes into the tank.
Only model left that has yet to solve this problem is the Red
Max based T435. Still see them lose the fuel filter in the tank
and then clog the carb screen with sawdust.
