I'm gonna throw this in there.......A few years ago I decided to give Aviation 100LL fuel a try. Can't say it helped a lot, but one thing I noticed was that after the car sat for a week or so, I either couldn't get fuel in the bowls, or on the other side of the coin...it would flood. Did some research and came to the conclusion that Av gas is too "Dry".....the needles would stick. Started using 94 pump gas again and the problem stopped. Just saying....
