I made a lot of progress today. I ended up replacing the servos and receiver to make it work with my JR transmitter. All the control surfaces work as they should. I also filled the tank partially with fuel and tried to start the engine and to my surprise it rumbled to life immediately. It seems to run well but as soon as I remove the glow plug driver it dies. Here is the glow plug that came in the engine. It looks fouled probably from the WD-40 bath the engine received. I am guessing it's the original one. What is the story on these types of plugs with the bar through them. I also have a number 6 plug and was wondering if it is okay to use in this O.S FP Max engine? What is the ideal mixture setting, 1 and 3/4 turns?
