My engine will stall if I use/press the brakes on my transmitter, which also closes the air intake on the carb. I need to know what is wrong! Is it my carb.? I have adjusted the idle needle on it, which has helped, but if I initiate the brakes for more than 2-3 seconds, the engine will just stall. I have brand new/just bought today Byrons Originals 10% Nitro fuel, brand new fuel tubing/line, and a brand new glow plug. The engine runs great except when it stalls. What is wrong? -Thanks
