Hello
I've had a nightmare setting my webra 1.20 with perry pump
To make story short after wasting many weekends and no flying I installed the attached return line to avoid excess fule in my carb, then the engine in idle mid range and full throttle was running beutifully.
With the nose up the engine was too lean and did not get enough fuel , regardless how open did I have the High speed needle valve.
Then I quit and returned to the original set (no return line) and used a perry carburator, same excess fuel , I have no idle at all with all idle disc closed , i had to guess 'cause the idle disc does not have an end.
Is there anything wrong with my return line?
I forgot to say That I fill the tank through the clunk by unpugging the filter so I would prefer keep it as a two way tank
I've seen many diagrams , I notice that inb some cases the fuel returns to the fuel line and in my case it returns to the tank, could that be the difference? and I don't see whay in my case the engine would run lean but IT DID so I would take any advice so I can sleep

Regards and thanks in advance
Sorry for my sketching I always sucked in drawing
