Re: No Ported Vacuum
Hi Bill,
I think on all carburated cars there's the venturi vacuum, and
located at the venturi level, that's the area that shrinks down to
create a draw to suck the gasoline out of the float bowls, as the full
vacuum should be call manifold, and that port should be below the
throttle butterfly plates.

Re: No Ported Vacuum
The Jeep is an '88 YJ that has been tagged as a "Tampered/gross-polluter"
after three failed California smog inspections. Even if I could pass
without the EGR valve, I would still like to understand why I have no ported
vacuum. The port I am referring to is the one just above part #60 in the
diagram at this link... http://www.carburetorfactory.com/expvw03.html. I
have sprayed cleaner in it and it is not blocked. Even if I rev the engine
to 2500rpm, there is zero vacuum. I am checking it directly at the port not
at the EGR end so there are no leaky hoses or valves getting in the way.
What am I missing here? Is there another port that provides ported vacuum?
Thanks again,
Steve

Re: No Ported Vacuum
That's the venturi vacuum, put a gauge on it and should read about
half your fifteen to seventeen inches of mercury at about three grand,
if it's designed like a Ford or Holley. If not the bowl gasket may have
been put in upside down to block that port:

Re: No Ported Vacuum
Hi Steve,
The Exhaust Gases Recycling valve is not very important for
Kalifornia, it just needs to look like it works, for the visual. What
makes the a polluter pass is a new unclogged catalytic converter, that's
job to chemically changes pollutants like carbon monoxide (CO),
hydrocarbons (HC), oxides of Nitrogen (NOx) and particulate matter (PM)
into harmless substances like carbon dioxide (CO2), nitrogen (N2), and
water vapor (H2O). My Bronco with over three hundred and fifty thousand
miles on it without ever having the heads off:
