Re: IML: distributor timing

["Frederick Joslin" <fljoslin@xxxxxxxx>]

Hi Chris:

I posted recently about not having success installing a Pertronix II electronic ignition on my 69 LeBaron 440. I could not get the timing to set and stay steady and may have damaged the distributor during the ignition install since it seemed to run pretty well before!

A new (not rebuilt) Mopar distributor fixed the problem and the orange ECU and 45KV coil smoke (not literally). I would look to the distributor and then the timing chain.    

Good luck.

Hi all, I need a clarification on timing with a light on my 67 Imperial 440.
When at idle with the vacuum advance
disconnected I get a steady strobe image on
the 6 degree before mark. However, if I rev the
motor to a steady say 1500 or there abouts the
mark moves but doesn't hold rock steady..it
jumps around a little bit about a half an inch.

If I hook my advance back up and rev to full
advance it advances but doesn't hold steady.
Should these readings be ROCK steady or close
to rock steady?

As some of you probably know, I'm still have an
erratic running engine that comes and goes as
it pleases. The distributor I replaced from
Kragen's (I know I'm going hear it about that)
because of this problem but it's still there.
A mechanic told me the "new" one could have a
bad vacuum advance and or sticking or improper
tension advance springs.

What should I look for?

Thx,
Chris Strohmeyer
