Hey Jeff. Was great to meet you in Alb. Hope to see ya soon.

Agree it sounds like a fuel draw prob. I haven't had that prob with my Dz's. Wonder if your clunk line is too short or too flexible??

When I was first learning the Dz I would get it too lean(I think) and 1/2 way through the flight it would just die. I would adjust the regulator and it would improve. Can't remember which way I adjusted though.

Hope you get it fixed.
