Default Hpi trophy 3.5v2

I just picked one of these up and it's been hell. This is my 3rd nitro. I had a Jato 3.3 and a savage 4.6 and both broken in and tuned fine. This one has been a joke. Spits and sputters constantly stalls. Took 3 days to get 2 tanks of fuel through it. Even at the factory carb settings it won't stay running. If I do get it to idle soon as it warms up it will race the engine randomly. Even with the throttle closed aside from the small idle gap. I did get it settle down a bit but now it's just randomly surging. I uploaded a short vid to YouTube. Any help would be appreciated.
