OK so let me first say hi to everyone out there ;-) I'm a new guy trying to get into the RC Truck hobby so my son and I can have some fun as he gets older. He's 3 at the moment and loves his little electric RC Car.
I bought a used DuraTrax Warhead that was upgraded to the EVO model and has a few other upgrades on it as well, but this thing just flat out refuses to start.
Here is what I have done thus far:
-Fully Charge my Glow Plug Ignitor and tested it on a plug screwed into my plug wrench. Glows up nicely.
-Put brand new Batteries in both the radio and the truck receiver (Energizer rechargeable made for digi cams)
-Emptied the old fuel and filled the tank with fresh O'Donnell 20% Nitro
-Reset the High Speed Screw to 4 turns out from fully seated (recommended by an RC Buddy)
-Reset the Low Speed Idle to 1.5 turns out from fully seated, and also tried flush with the ball knob (RC Buddy recommended)
-Adjusted the Idle Screw out in 1/8th increments to see if it would fire
-Removed the motor and disassembled it to see if it was gunked up. Looked clean to me, but seems like an ounce or so of Nitro came out of the bottom end and/or Exhaust Port, but the piston crown seemed to be dry.
-Replaced all the fuel lines
I'm out of ideas except to bring it to a Hobby Shop and have them get it running. The motor seems to have good compression, but I have not tested for leaks as of yet. It appears as though no fuel is making it to the glow plug (assumption here). I used to race motocross so I know a fair share about 2-stroke motors since I used to rebuild them all the time. RC Motors are a tad different, but same concept.
Any help anyone can offer would be GREATLY appreciated. I can snap pics of anything as needed as well ;-)
Thanks!
Scott
