brand new DA, and I do have over a foot between engine and receiver for the wires. All that is going to the engine box is fuel tubing and two nylon pushrods. I have battery mounted to one side of engine box, and ignition to the other. I'll try a new spark plug and see what happens. I know all the servos are all good and receiver, only get it with engine running. Going to try to mount everything in even more foam and keep trying.

Just starting to get a little frustrated with this problem.
