Also in the last pic. Ignore the red arrow. But the smaller line thats "T" and goes behind the yellow arrow....it goes to the distributer

The distributor should Not have full manifold vacuum to it, it should have, what I have heard call, Ported Vacuum. The hose for it should come from some place on the Carb., may be the blue cap there marked as "S" on the drawing, but, i have not researched the vacuum lines on a Weber in a while. I think that Large port on the front of the Carb. with the 2" hose and bolt plugging it, should go to the PCV on the Front Top of your valve cover. Hopefully some one will come along and know for sure.

yes...in the picture with the RED arrow ( i had taken this pic when i just got the motor and this is how it was set up)...after research i found that that is were the PCV line goes and so thats how i got it hooked up...im having to UNDO what the PO had done since he obviously didnt understand that vac lines, the motor runs great it just will not idle after the initial warm up and u unchoke it

i still have the charcoal can, it was never removed. it only has 2 lines hooked up at the moment, the fuel return line and im thinking the carb vent....but unless im over looking it, i dont see another line hooked up on the carb any where.

I think you still have full intake manifold vacuum to the distributor, if so, that is not right,. with full vacuum at idle, the timing will be too many degs. BTDC.

The vacuum advance for the distributor is supposed to be on a ported line. Quick way to test the line its on...start the motor, take the vac line off going to the dist., if the tube that you took the line off of has any vac, then its the wrong tube.

Vacuum advance works to advance timing when you are on the throttle, NOT when you are idling. If the motor is at an idle, the line going to the dist wont have any vacuum on it.
