[QUOTE="Tazza, post: 26252, member: 82"] Never worked on a JD, it could be so many things. Spun big end bearing will make a knocking sound, fuel detonating can make a knock too. As you say the RPM changes, you may want to check the injectors just to be sure they are not dripping. The govenor should hold the RPM pretty well rite though. Sorry, thats all i got without seeing it.... [/QUOTE]
