I have a chattering problem at the moment due to contamination of the clutch plate. When I get the oil leak fixed I will put in a new disc. I find that parking it with the clutch held in with a piece of wood, seems to dry it out some.
My chatter can be quite violent and I think this is due to the harsh suspension in the back. In my case if I slip it more it makes the problem much worse. My method is to get it slightly rolling and then let off the gas, let out the clutch and then give her gas. On a hill I have to use bull low.
