Physically Impossible

Two comments:
- I left some E10 in a metal tin overnight in the garage. Next morning, there were a few water globules about the size of rice grains in the bottom of the tin. I thought I had not properly cleaned out the tin....
So I completely cleaned the tin & left E10 in it again overnight. More water in it next morning. No E10 for me in carbed engines...
- Hard to start after standing overnight or after heat soak. The higher fractions of the fuel 'boil' off from the heat. What is left is less combustible & engine doesn't want to fire up.
