Webra 1.45 problem

[Gordon Anderson]

I was going to try a F plug today but I gave up too soon. Do you think that
would make the difference??

Plug should be an OS F.
 
How many turns out is your needle?

I'm having a problem with my Webra 1.45 and I hope someone can help me out. I
have a new Hydeout (thanks to the guys that gave me the control throw advice!)
with a new Webra 1.45. Below are the details on the motor setup:

Prop: APC 17x2 
Fuel: Magnum #1 
Plug: OS #8 
Pipe: Greves 
Mount: Hyde type soft mount and nose ring 
Tank: Tetra 20oz, on CG of model 
I have about 2/3 of a gallon of fuel run through the motor, this Webra uses the
regular carb with the high speed and low speed needles.

The problem is the motor dies when I roll from inverted to upright. This happens
mostly after I have been at idle for a while. I'm flying the advanced routine
and it dies during the roll out on the bunt and the bottom of the double I even
the slow roll. I have never made it more than about 3 minutes into a flight.

It seems to run fine on the down lines at idle, like in the stall turns and the
outside square loop. 
When it dies it sounds like someone pulled the fuel line off the engine, it just
un winds. We tried leaning the low speed needle, replaced the tank internal fuel
line to the clunk.

Any advice?
