Not trying to prove anything just an FYI.Some of the damage was mechanical as a
result of me trying to remove them. One was leaking badly on the car the other
had not started but both were very brittle especially around the inner part
probably since the outer edge was clamped between the flanges on the carb body
and somewhat isolated from the fuel. I looked around before buying new ones and
bought the ones that claimed to have Viton diaphragms. I am familiar with this
material as in my past employment it was the only material compatible with
methanol.

Ugh. That damage may well have been caused by ethanol, but I'm a
born skeptic with a little scientific training. Without a control
sample you can't prove the damage was caused by ethanol (but
again, it may well have been). I just changed out a set in my
HD8s that had been in over 25 years and all I saw was some tiny
cracking, and I live in California and I think we've had gasahol
longer than most states.Some of that damage looks mechanical to me; it could
simply be
defective parts. I would hope manufacturers are making parts from
ethanol-resistant rubber, because I just put in a new set that
look just like those.Bob

FYI, here are my HD6 jets after being exposed to todays gas
for approx 4 years. Will definitely use non ethanol fuel
whenever possible from now on.
