I have an old brass 3 port fuel selector on my plane and the handle seems quite stiff; partially due to location but it has recently taken two hands to turn in flight. Obviously this is not acceptable.
I found a schematic in the archives and plan to disassemble and lube it, but before I do, do I need to drain the tanks? This is for a taildragger, if that makes a difference.
