I have had the same problem as Kim from the time I bought the plane in January. The new restrictor fitting seemed to fix the problem for a few hours until the problem returned. I've just had all the tanks drained and the lines brown out--the mechanic said there was "schmutz" in the line which could have caused the intermittent problem. Will fuel her up and fly her after the 4th and report back. This has been a damn annoying problem and I share Kim's frustration.
