Re: [Chrysler300] 300G idling problem

[Ray Jones <hurst300@xxxxxxxxxxx>]

Back in the day, I used to be good at setting up muti-carbs. I used a 
Uni-syn.  I think John Lazenby's business still  sells them.
  I haven't seen anything here on balancing the carbs so the air flow of 
each is the same, but that can cause hunting in some applications.

I never did mopars, but I did many Boat and VW/Porsche Modified and 
Racing engines. It could  really make a difference, and seemed easy to 
me.

Kenny,

  I strongly suggest that you get a copy of the "G" supplement to the 
service manual. This is a Service Bulletin (Number 61-10) specific to 
the G. The vast majority of it is dedicated to the set up and tuning of 
the rams.

  I doubt there is a vacuum leak. Nor is it in any way related to the 
Pertronix.

  I had a similar issue with my G a couple of years ago. What I learned 
was that this car is VERY sensitive to timing and carb changes. Much 
more so than other cars I have had. A change in one thing prompts a 
significant change with the other. I spent a long time working this out 
and the Service Bulletin provided the needed starting point. I should 
point out that my car also has the Pertronix conversion which I am very 
happy with.

  As others have pointed out, the Anti-Stall device is probably changing 
the idle, but it is merely reacting to the conditions which exist 
(timing off and/or carb settings).

  The service bulletins pop up on ebay and the bigger literature dealers 
have copies of them as well.

  Good luck.

  Hey group,

  I have an issue with my '61 G and am hoping for some diagnostic 
advice. The
  car is completely stock, except for an electronic ignition (Pertronix I
  believe).

  When idling after warm up, the idle fluctuates, like a wave, up and 
down, as
  if somebody where nudging the accelerator pedal up and down. This, and 
an
  apparent vacuum leak coming from somewhere that hasn't been identified 
yet
  (or maybe they're the same issue), seem to be contributing to a 
stalling
  problem when stopped, especially problematic when switching gears, 
like in a
  parking lot (not a problem when driving at speed though, only when 
idling).
  I don't have the facility or equipment for this kind of work, so my 
mechanic
  is working on it, and going through the step by step process of 
elimination
  to figure it out. He's already replaced the distributor cap (worn) and
  spark plugs (fouled, and wrong kind of plugs according to him).

  Just thought I'd see if anybody has had any experience with this 
particular
  issue(s) and might offer some advice to help in locating the problem. 
Thank
  you in advance. Have a great weekend.
