Personally, I find myself getting a bit pissed about this fuel problem. My mower started to misbehave. I removed the carb and when I took the steel bowl off the bottom, the bottom 1/8″ was rusted on the _inside_. I keep the tank full, stabil in it, and run it every 30 days during the winter. Fuel tank had zero water when I carefully drained to check. Yet carb bowl had a small amount of “crud” that might have been water or water/alcohol or whatever. I dont see the point in adding ethanol, which costs more than gasoline on a per-gallon basis as well as containing about 70% off the energy in an equivalent volume of gasoline. Used to be “it is cheaper” although it never really was. But it is certainly damaging things here and there. I have seen this same kind of issue in a family members Johnson we worked on a couple of weeks ago. It is becoming more and more common. EPA claims “oxygenated fuel” burns cleaner. I think it just sells corn. We are getting the short end of the stick just as we did with the R12 to R134a refrigerant change. Too much chlorine in the air from R12, they said. Then we discover that over 99% of the free chlorine in the air comes from salt water in the oceans. Wheres the giant plastic film to cover the oceans and stop this stuff? Instead we get a refrigerant that operates at higher pressures, is harder on aluminum evaporator cores (how many friend do you have that have had their evap core replaced after less than 5 years? Compare this to 20 years ago with R12.) Steel is a common material in motors. It needs oxygen to rust. It cant get it from gasoline. But it can get it from alcohol or a mixture of alcohol/water and we know how alcohol attracts water. Just take a glass of rubbing alcohol and start pouring water in. It seems to disapper and the level in the glass rises far more slowly than you would think. This might be one advantage to pre-mixing gas/oil in the tank, you at least get a film of oil on everything to help protect against the alcohol/water that is always going to be present with modern fuels. vent off. 2008 Pantera Classic2014 Mercury Pro XS 200
