Webra 1.45 problem

[Gordon Anderson]

Bob,
 
I did replace the line inside the tank with new tubing, did not seem to make any
difference. It burns so little fuel that non of the lines in the tank ever get
un covered.

Make sure your clunk inside the tank isn't tangling up on the vent line, or
touching the back of the tank, OR that there's a hole in the fuel pickup line
where it goes on the tube in the stopper.....any of those would cause a
time-into-flight failure...

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?
