OS.91 SZ H-PS runs lean on 1/2 tank
I have 7 flights on my x-spec with New OS> 91SZ-H PS with MP2. The motor runs OK until the fuel tank gets below 1/2 full then it starts to run lean in tic tocs rolls and flips. I turn the main setting out 1.75 and the hover needle 1/2 to .75 and the motor still runs lean. It seems like the tank is not being pressurized enough to keep the fuel flowing to the pump. I check all the line for holes and leaks. I blew thew the pump on the motor and check the pressure line that plug in the back of the pump. I'm running out of things to look for, Maybe some ran into this problem before and can help me out or point me in the right direction.
There's nothing like a good challenge

Muffler pressure + pump or open vent?
