thx for the faster answer!

the engine run before, but something like 2-3 minutes with a low power, when the engine begin to make hard start, when he start he try to make overspeed with a complete close carbs.

i know for now the only method i see to start the engine is with a electrical (3600rpm drill) and when he start is run like full throttle for 25 second with a close carbs.

the glowplug ignitor is reaaly good and glow plugs too, i dont see any leakoff from carbs or header and the muffler is good (i reseal the exhaust manifold with cinetic liquid high temp gasket maker from permatex (a kind of really heavy lock tite)

what is the lsn and hsn exactly?? ( i dont know exact term they used in r/c world)

what can happens if the radio or truck battery is off ?? they dont supposed to work?? someone tell to me to check the battery but all servo work normaly....
