Re: Ok, time to fix some leaks for good. Help!

Switched out the coils, no noticable difference in how it ran.
Now I'm seriously grasping at straws... Was searching some other forums about fouled plugs and came across this:
"This may sound stupid, but are your vacuum lines hooked up correctly? If you accidentally hook the one end of the vacuum line between the carbs to an overflow, you'll run lean on 1 cylinder and foul another."
My middle carb runs lean, left runs rich so I started looking at the lines. Fuel line between middle and left carb? Check. Overflow line between middle and left carb? Check. Vacuum line between middle and left carb? Hmm... Then I started looking for diagrams or photos showing how it should be to confirm and came up empty.
Here's what is there on my bike. A vacuum line connects from the petcock to the carb plate. From the carb plate there is a vacuum line to the center carb. The center carb is connected to the right carb with fuel, overflow (split in center with drip line), and vacuum. The center carb is connected to the left carb with just fuel and overflow (split in center with drip line) - no vacuum! Is that correct? I don't find anywhere on the left carb where a vacuum line could connect...it's plugged internally where it would. Seems weird...
