When you removed the spark plug, was it wet, dry oily?
The spark plug wasn't wet. It did have some black carbon on it. I have another RV with identical Onan generator that is working fine. I pulled the spark plug from that one and tried it in this generator that isn't working. Still not working. I did the spark test and it is generating a rapid spark as it is cranking.
