Is this one supposed to react with the ignition switch, or react with the A/C cycling? Or Both? It gave no reaction to the ignition switch last night. I didn't start it again last night to check, but I suspect it does react to the A/C, as my idle never barely dips when it cycles.
The best I can tell, the accelerator pump has kicked the bucket. Perhaps the floats, as well. The condition has deteriorated to where the car is extremely hard to start, hot or cold. When it does fire, it's running very rich. I'm getting a lot of gray smoke for a few minutes. Just last week, it fired instantly when cold with one kick of the throttle, and ran well once warm, so I'm guessing the rubber & leather haven't enjoyed their re-awakening from sitting in someone's driveway for 5 years.
I don't have the time, garage space, or enough experience with carbs to feel comfortable enough tinkering with it, so I ordered a new one. I'm thinking $200 from RockAuto is going to be cheaper than having someone repair the old one. Labor rates are pretty high, even at the local mechanic. 2 bolts, a few vacuum hoses, and the linkage are all I have to deal with if I just replace it.
Thanks for your help guys.
hey wylie! you're most welcome for the help (my part) that I could give ya! never knew years later I'd be giving advice about that engine, very cool. And yup, I was nodding my head yes when you began to describe that it won't even stay running now. Exactly the same thing that happened with mine. Hey, at least I was able to tell you what it would do! When you mentioned running rich, I do remember that I was adjusting the air/fuel mixture screw A LOT! Until I had that accelerator pump diaphragm replaced.
I also agree with Trav, even on modern/current parts, remanufactured is a [censored]-shoot. Lots of junk out there. I can only imagine the lack of current knowledge about carbs is even less.
I did a quick search online and I have NO idea what Holley would charge, but.. They do offer rebuild services for your carb (they said Motorcraft oem)! I believe it's a Holley 1946 model on your 3.3L. Wouldn't hurt to give them a call and ask them how much that service would be. Better to repair the part ya know instead of one ya dont.. Just saying.

What's cool is if Holley charges a fair price, they are the manufacturer and would probably do the best job. And I doubt it would be $200.. but hey give 'em a call, see for yourself.
