I had the same problem when using Control E. I found that you need to turn the fuel thing just to the right of the left hand seat on by twisting it up or the fuel flow stops. Sorry, I don't know the technical names off the top of my head...
I figured out the roll to the left. By default, the pilot's weight (170 lbs I believe) is set to the left seat. There is no one in the far right passenger seat. If you put the equivalent weight to the far right passenger ... the roll will stop. It took me a while to figure this out!
My First machine ever. 64 K RAM (with the add on piece on back). Memories!
My first flight sim was FS1 on a 386 with 4 MB ram and a 20 MB Hard Drive. It ran off a floppy. Things have moved a bit in the past few years!
