Hi Randy,

I think I had the needle at 3.5 turns. One thing I just realized as I was thinking about the plane while at work......... is that I think I have the fuel tank exit higher than the carb. The motor is mounted inverted.

Could that be part of my problem ?

Yes.
If the tank outlet is higher than the carb, it could cause fuel to siphon and extinguish the glow plug. Check and see if you are at least getting fuel to the carb, and go from there. You may need a regulator or lower the tank some.
