    I'm working on a '77 Lincoln Continental with a 460 4v. It definitely needs a carb rebuild, 'cause it runs fine when I put my Maverick carb on it and the Motorcraft carb is leaking like hell from every gasket I can see.

    I've rebuilt a couple of Holleys, several Edelbrock/AFB's, and a few other random OEM carbs here and there, but never one of these. Any tips? Are there any common rookie mistakes I should avoid, special areas I should pay attention to, microscopic clock springs that will launch themselves to the moon if I take it apart in the wrong order?

    Thanks!

    Toss a Holley on it and call it a day?

    Yeah, I said something like that at first... Dude would prefer to keep it as original as possible though. You'd probably agree if you saw it. This guy has a thing for 70's-early 80's American luxury cars. It's not what I'm into, but I admire his collection. A few of them are especially rare, this particular one is one of 300 with a factory moon roof. It's pretty cool. Makes me nervous though - it's too big for my garage, so it sits outside. All it would take is one rock thrown from a mower and there goes a huge irreplaceable piece of glass. I'll be glad when it's out of here...

    It's been stored a few years, I've been "refreshing" it under the hood and getting it roadworthy again. All I have left to do is a radiator flush, oil change, plug wires, thermostat, water pump, replace a few decrepit vacuum and heater hoses, and this carb.

    I've got it put back together now. Turns out it's a lot like an Edelbrock/AFB overall. It seems like there's more to stick and get gummed up though, and it's got a couple of pointless complications I don't like. It's almost like an AFB and a Quadrajet got drunk and had a bastard lovechild.

    It works though! I bolted it onto the Maverick to test it out. Since everything else works on that car I'll know it's the carb if it doesn't run right. It idles and revs, but I'll have to wait a few hours before I can drive it. If all goes well I will swap the carbs back around.
