Like sparky said " check for air bubbles." I have an earth quake and placed a 2x4 under it, instead of running it around in a circle. I did this for the first tank just to break in the first tank. If the glow igniter keeps it going , don't worry. Keep it on for a 1/4 to 1/2 throttle, just to get it going. When I placed it on a 2x4 or something that will allow the tires to run freely, it allowed me to see if any bubbles were on the line. If you see the bubbles, watch as it goes into the carb, when this happens you will notice the engine dying down, this is an indicater that the fuel line needs replacement. I myself replaced the lines on my Caldera and my T-Max, it happens even on new vehicles. I own airplanes and the fuel lines are no different. I have other nitro vehicles and keep a roll of line just in case. Earthquake is a very strong and dependable truck. Beleive me I know because I run mine like crazy and it stands up to my other r/c trucks. These things happen to any and all other vehicles.
