E10 is everywhere here. Most common used fuel around here is the 89 octane petrol [R+M]/2 and I have seen no problem using it. It not as much the Ethanol that but is all the additives in the fuels around here. Plastic lines (Tygon) just don't like fuels. I do replace a lot of metering diaphragms here so much that I stock them for the Walbro and Zama carburetors so I don't break carburetor kit just for one. One of the things I finding on some trimmers and chainsaws is that the metering levers are not set correctly from the factory which is causing problems. Walbro now has two different W metering lever setting tools as the newer carbs have different settings. So far Zama is still using the Z tool for all their carburetors.
Also a lot of the clones look to use the same metering diaphragms as the Walbro and Zama. Be careful they are not all using the same design as the Walbro and Zama carburetors.
