Question, is the idle tube assembly on a BBD 8340 the same as that of a 8384? I have an 8384 I use for parts and a teaching aid. I need to pull the tubes out of the BBD in my J10 and clean them. Thought I would switch them. I bored out each to .032 but I did see one video that bored them out to .037? How has that worked for others?
Thanks and Happy New Year Marc
