Ignition ID

[Basoline]

So, I think we found the cause of a list of problems that was haunting my car but we're not sure...

The lever of the vacuum chamber of my ignition has a "2" marked on the inside. What does it mean and, is this a correct ignition for a stock+ engine?

Symptoms:
- running hot in trafic
- stottering at low rpm
- lazy on throttle

Setup:
- 383 4bbl
- 4speed

We also removed the MSD Blaster 2 and replaced it with an original. Comes with chrome ECU (yeah i know).

Do you mean the vacuum advance on the distributor? Not sure about the number 2 on the lever but the symptoms sound like they could be timing related.

Yes, i mean the vacuum advance.

Could be too little initial timing... that would cause the sluggish stutter at low rpms.

Try advancing the timing a bit, see if it helps. What kind of distributor do you have?

It looks original but isn't ofcourse because it's electronic ignition. Looks like a aftermarket race-ish thing.
