The Stovebolt Site Forums The Shop Area Engine Shop 1961 235 : question about Rochester carb.?

I have a 235 that I'm wanting to put one of my carbs on.

What I have is a 61 235 with a Rochester carb.. The only numbers I can find are on the bottom of the bowl and they are 7025382-c-26. can you tell me what I have from those numbers?

The carb. has been sitting for some time, should I automatically rebuild it or just inspect, what should I look for? Is the Rochester a good choice or should I look for something else?

By the way it's going into my 41 chevy.

Thanks, Dave

carbking, you out there???

The model 'B' Rochester has many faces and close but no cigar on the air horn and or throttle body specs. The late model 'B' has the bronze filter air horn. {manual or auto choke} is an option. The model 'B' specs I list has the 2 15/16 inch throttle body. 7024561 is the body for the manual choke. I don't think 2 15/16 throttle body will fit on your '41 intake.
My personal choice for the 216 / 235 inline six is the model 'B' Rochester.
Inspect and check if the carb will mount on the stud bolt pattern. If it fits, I will suggest rebuilding the Rochester.
I have issues with the complicated Carter. Hope I have been of some help. Good luck with your project '41.

Dave, I do not wear the badge 'carbking', but will fess up "son of the royal kin" where classic iron is concerned. Been old school for over 50 years.
If you make any other choice I suggested, I do have the Carter and also the Rochester. Send me some specs on the intake bolt pattern.

No problem with the intake bolt pattern, if I use this carb off of the 61 I'll use the intake and exhaust manifold with it, that's why I bought the engine, I needed intake and exhaust manifolds. I take it you sell carb rebuild kits? What information do I need to properly identify the carb to get the proper kit for it? Dave

I do not sell carb kits. The info you will need to identify the 'right' kit is the model numberfor the carb. The model number has been attatched to the air horn on a alum tab via screw. Good luck.

Yes, but no good answers on this one.

The identification number on Rochester B's is on a small triangular tag. Once the tag has been removed (commercial rebuild, purchased through FLAPS) the carb is extremely difficult to identify for a kit.

Some of the earliest B's had the last 4 digits of the tag number stamped in the airhorn gasket (original gasket only).

Not my favorite carburetor.

There was a protruding tab, which was part of the Air Horn gasket, that showed the last four digits of the Carburetor part number as well as the code date of manufacture.

Also, once the original Air Horn gasket was replaced, the last four digits of the Carburetor part number was to be stamped on the bottom side of the Throttle Body assembly. Also check for a casting # on the front of the throttle body.

There could be a casting number on the inside of the float bowl
and on the inside of the air horn. Recheck the air horn on the outside top area for a 4 digit number.

If you find anything, post it and maybe we can help identify from those numbers.

Keep in mind that when carbs were rebuilt sometimes the parts got mixed together and used with another carb. Recently I purchased what was being sold as a 235 carb because the throttle base mounting holes measured 2 15/16. When I opened the carb up all the parts/ casting numbers were for a 216. It also had a brass tag and the tag # was for a 216. So I had a 216 carb with a 235 base.
