Re: IML: 69 Won't pass emmissions



I'm wondering if the car mostly sitting the past 5 years is part of the problem? I would mostly let it run in the driveway & go around the block with it occasionally. When the original Holley got really bad, large amounts of black strong smelling exhaust starting blowing out the tailpipe & covering everything nearby. Perhaps, all that gunk is showing up on the reading? After replacing the carb, there was still some black coming out the tailpipe & making a spot in the driveway. That has now stopped.

John:
Great to hear that you got your car to pass. I would still look into
increasing the primary metering rods one size to improve your fuel
economy and reduce emmissions. Just for comparison, my '58 392 passed at
1.02% CO and 98 ppm HC on a well worn engine with the original carb
leaned out 1 step from stock.

I put on a Carter 9636 that I got from Jegs Performance. I finally got
it to
pass. I went in a different line this time. The tester told me " one
more
time through & they would need to put me on the payroll".
   The HC standard under load is 450 & it passed at 197. Idle standard
450,
passed at 256.
    The Co test under load is the one I was having trouble passing. The

standard 3.75 & finally passed at 3.69. Co idle standard 5.00 passed at
.46.

You didn't mention what kind of carb you're running. The idle test
failure when you leaned it out makes sense as you basically created a
lean misfire. The loaded test however has nothing to do with the idle
screws but with the power circuit. What were your loaded HC and NOx
numbers? If HC was a pass and the NOx was really low you might want to
increase the base timing. If the carb is new I would take it back to
the
supplier and have it replaced or at least have the primary cruise
metering circuit fixed. BTW up here in BC we pull the Air Care
licenses
of "friendly mechanics".

I did change the oil & filter 2 weeks ago. One thing I'm not sure of
is
on
the new carb, the instructions say to use one vacuum port for timed
advance
or the other for untimed advance. Since the car has dead when I
changed
the
carb, I couldn't tell for sure which one is correct.

John,

Always change the oil & filter right before you go. You did not
mention
having done that. Well, "always" = in the last 30 days or few
humdred

miles, whatever.  Also, make sure your tires are inflated to the max
allowable, so the engine's not pushing extra load.    Let us know if
any
of this helps.

I installed my new carb & the car runs nice now. I went for
emmissions &
it failed the CO test. The standard here is 3.75 under load. I got
4.30.
The idle standard is 5.0 & I got 2.18 on the first test.
    After some adjustments to the carb, the retest showed 3.77 under
load, just .02 away from passing & 1.07 at idle. Both big
improvements.
  Anybody have any suggestions to get this darned car to pass?
John
