That's the new AOC carb, zero carbon emissions when you burn water.

On second thought I'm not sure they put their food source in their fuel in the UK.

That’s hilarious Hopefully the people wake up and realize what in the hell did we do!
I have been seeing how you guys have been suffering with ethanol, it does seem like ethanol poisoning to me......

meh, nearest e free fuel is an hour from me, i use nothin but 87 pump gas. doesnt matter if its corn gas or not: leave it in ur saw for a year or arent careful with ur fuel cans youll end up with problems. some really bad fuel/water sat in that thing for a long time.
I concur with your reply. Mix in small batches, check what goes in your machines, run them dry if they’re not going to be used over long periods, these things won’t happen.
It's on a 550xp I have just finished rebuilding, carb looked mint externally, so I ran it through the laptop to reset it and gave it a go... It actually fired up and ran (very badly!) Its bonkers, as I have always been led to believe that oxygen is required for the process of corrosion to take place, am I right in thinking that !?!?I have learnt a lesson today... Don't judge a book by its cover....
Ya hard to get total depletion of oxygen.

rust happens anywhere, except for when theres a TOTAL lack of oxygen. the screw holding the lever must have not had a very good coating haha
Ethanol contains small amounts of H20, we all know what the 0 stands for. Run it dry, no problem.

Wow that is crazy rusty! I haven't seen the inside of carbs look that bad other than on salt water watercraft.
I learned recently you can find the rebuild part numbers on Zama's website and then order their rebuild kit and save a few bucks over the Husky kit. Hopefully that one is not beyond rebuildable. Actually, I can't remember if the 550xp is a Walbro or Zama but I thought it is a Zama...

Can't remember what make it is as I am back in the house now..
It is totally beyond repair, in fact I have already removed all the salvageable parts and used them to rebuild another carb. You are right, it does look like salt damage, on the pump side of the carb the aluminium has that frosted white corrosion like salt damaged aluminium. It's a strange one as the fuel tank showed no sign of muck, water or sediment, I'm thinking that the UK fuel industry is watering down the fuel with methanol like the US and this is going to be more of a recurring theme. Its a worry and pretty scary knowing how much these saws cost... The only upside is... it will keep me busy in the workshop!

Have you looked at seafoam ingredients, or googled it's ingredients? Is it magic in a can, like other quick fix, high priced snake oils?
