Default nitro 4tec 2.5

Well i had my nitro 4tec for a couple of years i have rebult the engine like 2 weeks ago. i broke it in how traxxas says to and it worked fine. but now i can get the engine to start. i have tried tuning it changeing the glow plug checked the fuellines it still dont wanna start. i am really getting sick of it i have spent the rest of my money on the piston sleeve and 3 new glowplugs and a new gallon of gas i have no clue whats going on with this car i cant afford to spend any money on it im thinking if no one can help with this its time for me to quit rc for a while.[&o]

It won't start at all, or it will start for a second but as soon as you take the starter off or give it throttle it cuts out?

I had a similar problem that turned out to be a blockage at the HSN. Worth a shot to take it out and blow it clean with wd-40.

Strip the engine down, flush everything out (needles etc) and check the fuel tank pickup...

Also check the fuel, temp range of the plug, glow starter etc.

Most definitely, also change you fuel and pressure lines. Then refill the tank, prime, and attempt to restart.

Return your needles to factory setting.
Try to restart and while you are restarting, slightly pull the trigger on your radio to slightly open the carb a little more. Once the engine begins to fire, let off the trigger so your engine will idle and not run away.
If your engine is stoill stubborn, try to leal a little (i\one 8th turn your high needle in) and try to restart again.
Keep ding this until your engine ignites and idles without stalling. Then warm up and retune to its old performance.
