hi SJN.
fuel filter is new and good, and hopefully not the problem.
Darryl, just thought I would see what other people thought of this issue, because before I brought the engine I was assured that the issues were only on the larger engine.
Its not a problem now I know,but nice to know if anyone else is experiencing the same thing with the smaller turbine.
throttle is set to soft.
hopefully will not be so humid next week and we can try again.
See you then.

Darryl J.
