Bizarre.
NT asked me to be honest, and I agreed, so I’m asking the same of you.
Do you believe that manufacturers haven’t figured out how to make gaskets and seals which work with ethanol?
They certainly have figured it out. BBBUUUUUTTTTT, I have many old vintage gas engines around here and now I should have to locate new made resistant gaskets, seals, TUBING, FLOATS, etc for these old engines then tear down each perfectly working engine and throw out perfectly good parts to replace them with new parts? My 1950 Evinrude dock-banger outboard probably isn’t a high priority item for gasket makers to jump right on and make new parts.
Look at many farms. There will be old tractors and a grain truck or dump truck that might get used once a year for ccertain chores. They work great. Fill er up with ethanol and you have the start of a scrap metal pile without rebuilding the engine either before or after the first tankful.
