RE: [DMCForum] crush washers on the fuel distributor

["John Hervey" <john@xxxxxxxxxxxxxxxx>]

Ok, On all topics,

I'm wondering how the ign system is going to do on a stock coil that was
rated at 12,000 volts and not much current. Watch out for the coil to
build
up heat as you drive it. If it looks like it's getting to hot, then you
may
want to upgrade to the Blaster or Pertronix. Does the lit say anything
about
coils and what ohmage should be run.

I don't think your pumps in danger unless it's very old because most all
make a noise. But, With your low voltage problem and the pump designed to
run on 12 + volts the motor would make more noise as the voltage drops.
Ever
notice a ceiling fan Humm that has a variable speed control as the voltage
is turned down.All electric motors will do this if your not within voltage
specifications of the volts it was designed to run on. If the low voltage
persist, that will have an effect on the pump over time. Your low voltage
still bothers me.

  Okay, thanks for the sizes.  It should't be too hard.  If I can't find
  them at a shop around the corner, I can head over to my mechanic's shop,
  where he's got 'em all.

  Sure, I do expect some fluctuation.  I was just trying to establish the
  sound I'm hearing as one that is fluctuating with voltage.  I don't
expect
  a silent fuel pump, either, so I'm not particularly worried that I'm
  hearing mine.  But should I have one on the way out, I'd rather figure
it
  out before I get stranded somewhere.  :)

  I never have found the source of my voltage issues.  Honestly, I've put
  that on the back burner because the car *does* work.  Certainly I expect
  to see lower voltages at idle, but I still don't like the fact that my
  radio cuts out at idle.  One of many things I plan to do at some point
is
  pull the center console out and get a better look at some of the
  electrical system up in the dash.  I know a previous owner has done a
lot
  of work in there, so someday I need to inventory everything in there and
  figure out just what is stock, what isn't, and why.

  I've got no reason to believe I have bad gas.  I'm using 93 octane, and
  only buy major brand names, and not always at the same station.  I've
got
  a couple of jugs of Sunoco 104 in the garage (for fun weekends with the
  other car).  Maybe I should toss a few gallons in the DMC and see if it
  manages to knock with that.  That is, if it can even ignite it at all.
:)

  I'm not expecting much, if anything, from the ignition upgrade stuff.  I
  know a lot of people claim it's snake oil, but since I enjoy tinkering
  with things, and it's fairly easy for me to get over to DMCH to pick up
  the parts, I figured I'd give it an unbiased opinion.  Hopefully I'll
  finish the install tomorrow.  I ran out of light today.

  Right now I'm still on the stock coil, which I assume is 20 years old.
I
  don't believe it was replaced when the performance engine was put in.  I
  plan to leave it as it is for the time being, at least until I've had
the
  opportunity to determine what, if any, is gained by adding the
performance
  ignition package.  After that point, I may well upgrade it.

  Since I have the performance engine, this may well just be a case of
  slightly too aggressive timing, so backing it off a little may also be
of
  some help.
