guys the JC is pretty simple on the rose, if you close it fully, then put your thumb on the DT lined up with some part of the mod and then turn the mod you can actually count the turns. basically just close the JC and then count one turn open or 2 turns open or 2 1/2 turns, etc... around 5 turns is fully open, by the time you hit the sixth turn it will be unscrewed...
once you do this you'll always know ~ where your ideal juice flow is, so if it's lets say 2.5 turns open all you have to do is unscrew the chimney and the tank at the same time, then when you reassemble you close the juice all the way then count 2.5 turns open to get right back to where you were. I usually run everything at ~ 3 turns open and I always can get right back to it
