Anything about a Rochester BC carb? I acquired one yesterday afternoon from an interesting old '63 Chevy Bel Air that's flipped over hanging off a cliff out in the middle of some woods (that's a story in itself). That car had a big straight 6 in it, I think a 235? This thing has a massive air horn compared to the Carter RBS I'm running now. It drops right on a 200 perfectly. I spent a few hours last night going through it, cleaning it and putting in a rebuild kit. Going to stick it on the Mav tomorrow and see what it does... If it actually works, it's going to be hilarious. It needed a good bit of cleaning, and pretty much everything on it was seized up, but it did sit in the woods for 30+ years. All in all it is the easiest carb I've ever rebuilt. Replaced all gaskets, needle and seat, accelerator pump and some check balls and springs. Float and everything was in great shape. Pics below of where I got it from... yes, that's where I found it, sitting right there on that intake manifold. It took 45 minutes just to get the hood open...
good luck! hope fully it works.... by the time your maverick is done it will be a chevy ......... almost........ J/K.
Not only does it run, it runs great!! No tuning or anything yet, I just slapped it on, primed the bowl, hit the key and it just fired right up and sit there and idled perfect. Throttle response is practically instant with no hesitation, popping, cracking or anything.. Just got to get the throttle cable hooked up some how and I can take it for drive. A factory Maverick Carter YF air cleaner base will even drop right on with a couple of small easy mods. If it runs as good down the road as it sounds sitting my driveway, it's staying on there.
Quite a few actually. The body itself isn't even really that bad. That rear bumper still looks practically new. It's got a 235 with a powerglide behind it. I'd love to get the whole thing out of there, but the only problem is it's about a mile back into some woods, up and down some pretty ridiculous hills. How it got there is beyond me. The first time we found the car was back in the early 90's, and it had already been there for a long time back then.
I remember you telling me about that car when you were up here I think. I would love to hear the story of how it got there. I bet money alcohol was involved somewhere in there. lol Sounds like it was an easy rebuild and it sounds like it's going to run good as well. I am still in a mental struggle rather I am going to try and get this 200 in my 72 running or just go straight to a 302. It is real complete and free spinning but the throttle shaft is stuck solid. I guess I need to pull the carb, tear it down and soak it. Good luck with it clint
Yea, I would love to know how it got there as well. As for stuck throttle shafts, every moving part of this carb was seized tight this time yesterday. I soaked it all with Marvel Mystery Oil and let it sit about 15 minutes. Then just started tapping around on it with a screw driver handle and got it all moving again. PB Blaster would probably work even better, but the Marvel Oil was just what was near at the time.
Or rebuild the one you have for 12 bucks.. Or ship it to me and I'll rebuild and test run it prior to shipping it back for $30... Got about 50 miles on the Rochester today. Runs real good, just a little rich. Need to step the main jet down some
NEAT! There is some sort of 40s era car next to my daughters school on it's side. Really makes you wonder why it's on it's side...who just leaves a car?
Seems like no one knows anything about this carb, what CFM or anything. Even posted on fordsix and haven't got any response. Played with the timing some today and swapped the main jet out of an old Carter YF into it. From a dead stop with the car at idle, there is a slight stumble if you mat the gas, but otherwise just normal driving around town and interstate driving it runs great. It has a heck of a lot more low end torque, it'll do the one wheel peel all day long. The stumble seems to be going away the more I drive it. It still smells like it's running rich, but the gas mileage seems to be great so far. Definitely an improvement in gas mileage around town. Just seems strange still after all those years having something like this that came off that Bel Air on my car. If I didn't pull it and rebuild it myself, I don't think I'd believe that's where it came from.
http://www.carburetorfactory.com/expvw21.html It is for the most part just a Rochester B series carburetor the differentiation between the two is the thermostatic choke that came standard on the BC series carburetors Here is an arcticle I found on a rebuild of the BC series carbs http://www.classictrucks.com/tech/0802ct_rochester_carburetor_rebuild/model_b_carburetor.html I have dealt with a few of the B series carbs, they are good carbs (rebuilt an 53 bel air) that and I have seen them on several flattys with two or three of them in a row they were one of the best single bbl carbs at the time.
Well, it's not much, but the Maverick had it's first kill today with the new carb. Mid 90's Chevy Suburban with big chrome wheels and stereo booming. He kept messing with me as we were driving down the road. Pulled up to a red light, when it went green we both stomped it. Smoked him off the line, then from about 40-55 we were both running even, he couldn't gain on me and I couldn't pull away any, then I pulled away from him on up to 80 and let off. Get to the next light and he asks what kind of car it is. Told him it's a ford Maverick, with a straight 6 in it. He goes "aww damn man, don't tell me that!"
