The chock pull off is attached to the side of the
carb. It has a linkage rod on 1 side & a vacuum line on the other
side of it. When the car starts warming up, the vacuum should pull the
diaphragm in to open the butterfly in the carb. If the pull off is closed &
not functioning, the car will run rough & there will be a lot of black smoke
coming out of the tailpipe.

I hate to have to ask this, but what is a choke
pull-off and how do you check it? I thought I had a Holly when I
wrote yesterday, but today found out it is a Carter.
Thanks,

If you have a choke pull off on your carb,
check to see that it is functioning. I had a 66 with the symptoms you
describe & that was all that was wrong with it.

Black smoke means a rich mixture. Choke being stuck, plugged air
filter, or stuck floats in the carb are common causes. It now probably
also needs to have the spark plugs cleaned/replaced.

CC was just delivered. I pumped the gas a
few times to set the choke on the 440 and my 67 Crown started
right up with the oil, fuel and alt guages immediately coming
to life. But she ran very rough. I figured it was because it
is cold (about 28 degrees) and gave it about 15 minutes
to warm up until I got a temp reading of about 20%. It
continued to run rough while dark (black) smoke exited the
back. As I listening to her idle I could hear it miss. I
put her in drive and rolled down off the small hill where she was
parked. When I put it in reverse to drive back up she started
to buck and stall so I gave it more gas. It sounded labored
the way a tired engine will sound but did make it back up.
I'm dissapointed and not at all sure it's any better now
than the last time I drove it.
In the hopes it's nothing too serious like
valves, heads etc, I'd like suggestions of what else it could be.
Here's a list of what they did;
new points and condenser
set ignition timing
adjusted carb
changed the plug I couldn't get to so now
it has all new plugs
with just over 100,000 miles and old gas.
I've read posts about old gas and am hoping
that's the culprit. There's
also a possibility I might have added more lead additive
than necessary.
Thanks in advance for your
suggestions.
