carbon build up

[Dan Stadt]

I'm new here so I apologize for bringing up what I'm sure is an old standard. I've used Redline and think maybe it helps. I've heard of using a can of motor oil in the tank. Brake fluid at fillups. Of course, driving wide open until carbon is gone or I'm in jail. Reaming out chambers through glow plug hole (I haven't found anything about that in the past listings here). I'm aware of the additives list, but I'm inquiring about the advantages and limitations of the more obscure solutions (particularly cleaning the prechambers mechanically).
Thanks for all the good information and particularly for the spirit of help and support.
