[NSRCA-discussion] 120 AC issues

[Paul LaChance]

Here is a stupid question, but what size prop are you running?  Is the engine fully broken in?  Just a thought.  Had similar issues with a 170 DZ.

  Stuart, 

  I had the same problem with a 91AC a few years ago, like Ron, it turned out to be the front bearing.

    Stuart,
    I've had the same problem before. It was the front bearing. The bearing heats up the front of the motor, then the regulator, vaporizing the fuel. Better known as vapor lock.

      I wouldn't have thought about the pipe.  I should have another.
      Thanks,
      Stuart

        Sure do.

        Try a different pipe. I know a flyer who had this same problem some years ago, not with an AC though. He tried everything and the problem kept hounding him. Turned out that the pipe was plugging up when it heated up and restricting the exhuast flow.
