Webra 1.45 problem

[David Harmon]

Gordon.you might check to see that the fuel line to the pump is not on
the vent line of the tank and the vent tube in the tank is pointing
toward the canopy.
If the line to the pump was on the tank vent and the internal vent pipe
was pointing toward the belly...
Hehehehe....don't laugh..I've done both several times.

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...

Subject: Webra 1.45 problem
 
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?
