[Bricklin] Idling question

[Greg Schroeder]

I was thinking about going to a stainless braided line since I would like to
have something that is better than the standard rubber hose.  I checked the
temps of the gas line, carb and intake.  The carb was around 156.  The intake
was at 115   The gas line was around 120.  I actually have the gas line
resting on top of the PCV hose to the front of the carb.  I have a new
mechanical fuel pump from the engine rebuild.  I had reset the carb floats to
spec from the rebuild kit.

I still have the original charcoal caniste and a new gas cap.  There is a lot
of vacuum at the gas cap.  After driving for several hours coming back from
Lexington I walked behind the car and I could hear the air being sucked in
around the cap.  Should I be concerned with this?

I am starting to lean towards the vacuum advance. The distributor is one thing
I have not replaced since the engine rebuild. I reset the timing yesterday by
vacuum with the vacuum advance disconnected and the hose attached to a vacuum
gage.  I set the timing based on the most consistent vacuum instead of the
highest vacuum as I had done before.  The car starts quickly cold or hot and I
was able to idle with the AC on and in drive for over 3 minutes before the
slightest hiccup in the idle.  I have read several articles on the internet
about the vacuum advance and smooth idle.  Below is a list of vacuum advance
benefits.

          1) Improved idle cooling
          2) Improved idle quality
          3) Improved fuel economy
          4) Improved throttle response
          5) Improved drivability
          6) Enables improved spark knock control under full throttle
accelerations
          7) Enables leaner fuel jetting at light load to further improve fuel
economy.

Since I have not replaced this it could not be functioning at it's optimum
causing this issue.  Would this be going the wrong direction?

  I use the same carb on my 360 also. I would think your problem lies in one
of two areas. Either your running out of gas or getting too much..
  I use stainless braided line between the engine mounted fuel pump and the
carb. This line insulates much better than the normal all steel or all rubber
hose.. No part of the hose should touch any part of the engine.. I.E. Don't
let it rest on the valve covers. This can cause vapor lock..
  Also are you running the stock charcoal cannister. The gas cap on the brick
is not vented and if you removed the charcoal cannister and plugged the hoses
you now have no way for the tank to vent, this will make it hard for your fuel
pump to "suck" out gas.
  The edelbrock carbs do not like high fuel pressure.. I use a mechanical high
volume carter pump with no  regulator..If you have an electric pump it is
probably putting too high a pressure and flooding the engine.
  The AFB style carbs also have had problems with the floats being set too
high out of the box.. I believe the manual calls for 7/16 inch float drop..

Larry,.

Thanks.  I will see if I can check this out easily.  I had rebuilt the carb
last year and everything was in spec then.
