Dizzy change

[Dave pitt]

Hi all,

I would like to fit a set of bike carbs to my 2.1. my question is will the vacuum advance retard dizzy work ok with this ? 

The vac pick up is still from the manifold but at x4 separate points..  

Or has anyone done a dizzy change to a none vac set-up ??

Hi Dave,

I tried both with and without vacuum on my 2B - pinto with twin 40s.  I found it better with vacuum at idle and on the overrun.  I used 2 small pipes from cylinders 2 & 3 into a in-line fuel filter (used as a small reservoir) then out to the dizzy.  It worked quite well and I ran it for a few years like that.

I eventually swapped to a fixed dizzy with an Aldon Amethyst ignition unit, but I still kept the vacuum system off the middle 2 cylinders.

Hope this helps,  Steve
