Tech top tip of the week : Ferrari 412 - vacuum hose microplex

This week I received the following update from someone who ran into this issue. On this blog there is not much tech advice but I just noticed I have this bloglabel called "fixit" (on the right side of the blog). So if you have anything useful to share for the community I'm happy to add it here and label it accordingly so you can look it up. Else I would suggest to post it on Ferrarichat. 

Check if the vacuum hose is connected to the microplex
This is usually forgotten
Most people don't even know
In my case the tube was just hanging in the engine compartment
The vacuum tube is connected to the cam cover and adjust the ignition timing (advance/retard)
