I have an Aftershock and I'm new to Nitro. I seem to have cleared up my issues with the slipper and the clutch. My current issue is tuning, I get it to start and idle fine, and when I pinch the fuel line it revs up for a second and then cuts out. I re-start and run without any smoke after initial acceleration, and then after about about 5-7 minutes it will stall out and I cannot restart it. I pull the glow plugs to see if I'm maybe getting flooded and that's not it. Any ideas would be greatly appreciated.
