Ive got this 70 stage1 carb and I am having trouble deciding what to do with it. The original finish is really pretty good. I am afraid to clean it heavily for fear of damaging that original look. It has some really nice original features. The green dot sticker is in great shape. It has a really cool Rochester Products sticker on it that Ive not seen before - anyone know its significance? The windup spring retains some original blue finish the secondary shaft in the baseplate has green coating that is virtually unblemished. The steel pieces and linkages still have good original looking yellow chromate finish. However, the throttle arm has been cut, so I will need to replace it. If I start replacing original parts with replated parts, or replate the originals, it sort of starts the gravitational pull of a full restoration. I think I am going to carefully clean it up, trying not to disturb the originality. I want to keep the stickers unblemished. I will have to swap on a throttle arm in similar condition is all. Any thoughts on this? Am I crazy to want to keep it really original? what is that RPD sticker? Your input is appreciated.
That looks like a cool time capsule for sure. I love the idea of cleaning it up and preserving the originality, then you can sell it to Jason! JK.
Thats a really nice carb. No idea what the sticker is. I would do a survivor rebuild on it leaving the original finish undisturbed for sure
Nice piece indeed. If I am reading correctly the date code is the 245th day of 1970 which might make this a service carb which might explain the RP sticker that I do not recall seeing on other carbs. However, I could be all wet on this.
Very nice - question for the gang - the gasket that is hanging out - is that correct? is there a reason for that? I have a carb with that as well and I always wondered.
its a nice clean carb if you are keeping it i would just fix whats broken and put a Quality rebuild kit in it. if you are gonna sell it i would just sell as is. not jumping on you jason but what is a survivor rebuild? charlie
I wonder if the logo font is indicative of a certain time period? I'm guessing it's a little new for a 1970 carb. It reminds me of a "reman" sticker, but Rochester Products never rebuilt carbs. I think they were done through Delco, by an independent rebuilder.
The airhorn to main body gasket appears to have been changed somewhere along the way with a gasket from a bit newer model carb then not cut back enough to resemble the correct look. Many carb rebuild kits include extra parts (or at least used to). I have used left over gaskets from other rebuilds when only this gasket was needed to save the customer a few bucks.
Damn, you beat me to it! Pretty sure the term “survivor rebuild” is now obsolete. It was changed awhile ago. Correct name in use now is “Jason rebuilt”. Who is CJay? cool carb!
Not much in the know on these things but first thought is its a reman that was just lucky enough to get a 70 main body. The sticker might be from where ever it was put together.
Although it might be just the pictures, but the zinc dichromate plating on the float bowl looks more like olive drab to me. Looks dark and thick. But who knows?
I thought that performance carbs like the 246 had an angle vent? Maybe the air horn had been changed?
It cleaned up pretty well. nylon toothbrush with some penetrant scrubbed the carbon off. The steel pieces I put in the vibratory tumbler with some polishing media. I rebuilt it stock with the exception of .035 idle tubes and a .134" inlet seat. i have never seen 7/8"-20 inlet threads this clean. They are as new. Must not have seen much use at all.
It was manufactured for a 1970 stage 1 factory installed, not service replacement. It HAS the 2 letter identifier, so i suspect it is a left over production unit that rochester sold as a service replacement (which could explain the rochester decal).
