This "lever" isn't familiar to any of us at MMI. Where did you get this EI?

Hi Bill,

This is a Pertronix Ignitor for 4 cylinder off the shelf at my local Lordco auto parts store here in Victoria, B.C., Canada.

The action on it didn't seem to change the gap between the EI module and the magnet ring. The EI module swung around the radius of the magnet ring. It made for finger tip adjustments to the timing.

I found it or at least something close

Here it is on a 6 cylinder Pertronix EI. It's simply a modified base plate. My only concern is what it does to the ignition protection requirement for our distributor.

A little more searching turned up a 4 cylinder model. Note that both mention vacuum advance.

For vacuum advance.

I get it now...used for vacuum advance. Sure is handy for fine tuning timing without sticking a wrench down into a hot engine though.

I'll let you know if it has a tendency to creep. I marked its position.

Has anyone retro fitted vacuum advance to an A4?

Another question:

Do electric fuel pump usually tick when operating. Mine seems to get pretty loud when idling. If I accelerate it will quiet down. Only when I slow down does it become louder.

It did this when I first jumped out the pump to prime the system before starting. It seemed to quiet down when it started to pump fuel but while it was trying to prime for the first time it ticked loudly.

Yes. This is normal for the FACET.
A little louder when first engaged and then more "muffled" once fuel begins to pass thru.

Hi,

On the topic of ignition protection....

How would the vacuum advance plate on these EI modules compromise ignition protection?

Is it because of the opening in the bottom of the distributor cap like when we modify them for the EI module wires? Would sealing the opening off after timing has been dialed in help with the ignition protection?
