We had a student that had similar problems with the EVO engine. It took a long time to get it to work worth a darn, but one of the things we ended up with was a hot glow plug. That seemed to make it happy so maybe you could try the same. Option B is to return the engine for a replacement. These engines are marketed as being ready to run right out of the box. Perhaps you should make the manufacturer live up to their claim. This is assuming, of course, that your fuel system has been checked out.
