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.
