ok, here are some pictures with explanations.
Basically i have now the lines connected as per Mark's suggestion excluding the emission line at the bottom of the distributor, that is now plugged.
When you say "excluding the emission line at the bottom of the distributor" is this what you are refering to? (see photo)
If so, this is to retard the timing, mine is now disconnected and plugged with a rubber cap.
In the first photo, is the vacuum pipe that is connected to the dashpot going into the vacuum on the bottom of the front carb?
If so, then someone just bypassed the two way valve, and that should work.
(Mine is currently going through the two way valve)
In the second photo, you CAN bypass the three way valve and hook one of the carbs vacuums into the top (advance) of the distributor.
That is how mine is currently connected.
As per testing the two and three way valves, I have no idea how to do that. We need some expert advice on this one please.
