Had my tmaxx out last night and it was dying after a high speed pass when i would let off throttle. Then i wud have to give ut alot of gas to start it. It progressivly got worse starting it almost full throttle to start. It was idleing fine an if i wud give it more then half throttle it wud sputter an die. Now i have fought with leak issues in the past on this motor an have sealed the motor and have new tank on it with new lines. And the glow plug was good. Kinda stumped here. Anybody got ideas or thoughts?
