    OK, well test equipment can oftentimes be deceptive and lead us down the wrong path? Does the engine sound like it is actually misfiring? Are you sure the timing is advancing fully and the economizer linkage is set up properly?
    Any chance of posting a video of the engine running/misbehaving?
