Stampede .12 engine
I have a Stampede with a Trx12 engine. i have just finished replacing the o-ring set in the carb. What happens now and before, was i would start the car, it would idle fine. I drive it till there is about 3/4 or half a tank left and when i would stop and idle it will just die. Trying to start it again is a mission as it just will not start. By holding the car upside down it sounds like it wants to start but doesn't. As far as i'm concerned the needle settings are fine as the car performs fine without overheating. I have replaced the piston/sleeve about 3 litres ago with a .12 piston kit. Any suggestions???

Sound's like its too lean to me. (Works fine at top of tank, but when the fuel level drops, the fuel pressure drops, and it leans the mixture out.). See if you can richen the needles to factory settings and run it. If you can't you probably have a crack in the tank. If it works at factory settings, tune it with the tank about 1/4 full next time.
Usually when the engine dies at half a tank, you got a pinhole in the pressure line. Try replacing that.
