[Mgb-v8] Carb to dizzy connection

[Bill Zenkus]

Hi Barrie

The passenger side vacuum port is ""timed" meaning vacuum increases with engine speed.

The drivers side port is the "full" vacuum port meaning the vacuum decreases as engine speed increases.

Determine if the dizzy requires increasing or decreasing vacuum to advance the timing then connect to the appropriate port.

If not sure how to check the dizzy, try using a hand vacuum pump connected to the dizzy with a timing light at idle. Watch to see if timing advances (increases degrees of timing before TDC) when applying more vacuum with the pump - if yes, go to the timed port.

I have an Edelbrock 1404 (manual choke) on my 3.5L Rover in the MGB GT
There are three spigots when facing from the front
The Roger Williams book says vacuum connection to the distributor 
(D&D Delco) is the right hand small outlet facing from front and 
middle one blanked off, and one the left blanked off.
My "shop" says the distributor should be connected to the one on the 
right -  and there it sits.
The Edelbrock Owner's Manual is no help.

So which is correct ????
