Definitely in agreement there...mine had sat for quite a few years when I got it. Every other time I drove it I had to replace the fuel filter until I got the tank cleaned. The guy said he had never seen that kind of crud come out of a gas tank before. Also, if you are running the original Holley(3667?), an Edelbrock carb will make a new car of it. I had the same symptoms. I spent a lot on the Holley and it didn't help. I think the edelbrock is a 1406 or 7...one has the choke on it and one doesn't. Bolt it on, hook it up, and drive away. It's a wunnerful thing. Had to pick up a few cents worth of screws, nuts and washers at the hardware store to help the linkage mate up. If you're a packrat like me you'll put the old holley on a shelf just to have. Keeps a clean spot on the shelf surface, too.

But, as I am sure someone on the list will suggest, you could by-pass the gas coming from the gas-tank and use some fresh gas that you could add directly into the input port of the carb(hope I am saying this right?) and if the car smooths out, well, its probably the gas itself, the filter or something in the tank that needs to be cleaned out. Just my 2 cents worth! Dan Melnik ---- Dan <sunup@xxxxxxxxxxxxx> wrote: ============= 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.
