RE: Bad Fuel - how?
Reminds me of my first gallon. Lasted me from 1991 to 1998, used only when I had a plane that was flyable. In '98, I used up the last of it (by then I had two .25 FP's) and bought some more, it was 10% Cool Power.
in 2003, one of my students had a jug of 15%, I forget the brand, but his OS .46 LA would not keep running. We finally tried some of my 10%, and it ran fine. Nobody else could keep their engines running on his new jug of 15%, so he trashed it and we speak now of certain bad jugs of fuel.
No explanation, I just assumed there was a manufacturing problem.
Good luck,
