Patrick,
While I can't answer your questions about the carb parts, I can give you a
tip about the fuel line. Instead of using vacuum line, I would suggest that
you go to a small enging parts store with the carb in hand. Tell them that
you need a piece of fuel line to go from (show them where) for a pair of
carbs. The stuff that they have is made for use with gasoline in a high
temperature, high vibration environment. (kind like below the carbs by the
exhaust manifold imho) I picked up a piece that was big enough to cut 3
lines from (always need a spare!) for about a buck! Beats the $22 for the
molded stuff. Also, this fuel line resists kinking (think about the insides
of a leaf blower or weed whacker - not much room) and comes in cool colors!
(mine are yellow.)
