Thanks so much for the great suggestion. I actually bought some radiator flush from Napa a little bit earlier and was wondering if that would be OK to use in the system?
Search this site for "How to Flush Cooling" systems. Contains suggestions on how to flush the Cub's block and bolster. Most liekly work on the B's thermosyphon cooling system where crud builds up around the rear cylinders.
