Anyone,

I have a P-51 Mustang PTS with an Evolution Trainer Power System (EVOE100) .40. I recently had to put on a new body [:@] as well as replace the Remote NV Assy 61NT. Now when I fly it the engine will quit while airborne. I have found that when I hold the A/C nose high at full power like it is in a steep to vertical climb the engine quits in about 30-60 seconds. I found the clunk okay and the tank appears to be air tight. As the engine fails I think I see air bubbles goin through the lines. From what I can tell from reading this and other forums it is either:

To Lean
the needle is not seated airtight

Anyother ideas??

Thanks,

Mike
