Nova Flyier Mine Saito takes a minute to warm up before I can get a descent idle (2000 RPM) . Even with pre- pressurizing the tank. Try to back out your low end 1/2 to 1/4 turn and see if it helps> I got a feeling you are somewhere around one turn in to lean. Make sure your trim setting on your TX is not two low. Try to keep it around 1800-2000 no lower or it will cut out and dye. Did you try the settings I gave you? that my engine is set at? Steve
