I'm a little curious on what a rebuilt carb actually will do for you. I understand that this is highly individual depending on the current condition of your carb, and how well it is set up. If you have an averagely used carb that has not been rebuilt for quite some time, and is not exactly tuned 100%. If I would hand this carb in to have it rebuilt, what could I expect? Anything? I have a few spare ones now on the shelf, should I try the other ones just to see what differenecs they would offer, or is it too much work to swap them around and get them adjusted and working properly? Sorry for the "fuzzy" question, but I'd like to get some more info on how important this is, and so forth. Many thanks..
Even a do-it-yourself carb rebuild can make a WORLD of difference. I've seen barely-running junkers that couldn't pass a gas station turn into tire-fryers by adding a carb kit 'n' float, and performing all the adjustments. You have it exactly right, it depends on the current condition of the carb, and how well suited it is to the engine combo. If you "hand this carb in to be rebuilt" and the rebuilder knows how do a) a proper rebuild, and b) tunes it to match your vehicle, you stand to gain tremendous benefit. If this is a stock engine, and the original carb, I'd suggest you buy a rebuild kit and a float, a couple cans of carb spray, and you'll have a nice weekend project. Follow the instructions in the kit, perform ALL the adjustments, and you'll be fine. Yeah, why not try the other carbs on the shelf??? At least you'll be re-acquainted with how they work. DO NOT overtighten the carb mounting bolts, especially the front ones on a Q-Jet.
A rebuild can make a lot of difference, but get a good book. My first q-jet rebuild resulted in a few leftover parts (opps). It still ran, and better than it did before the rebuild.
I've got that book, it still seems a bit complicated though. I'll just have to dig in, and take it slow..
Oh, you may also want to get a cheap (I mean toy-quality) camera (digital or polaroid). Either that or learn to sketch. Document your disassembly so its easier to put back together.
