The Stovebolt Site Forums The Shop Area Engine Shop Roch. "B" carb. questions

Hi, I'm rebuilding a Roch. B carb and the exploded view on the instructions show the fuel filter separating from the fitting and gaskets. The view provided is of a "BC" model. My filter won't separate, at least not easily and if I force it I'm afraid it might break. And I can't find one anywhere on the internet, not one in the rebuild kit either so I definitely don't want to break it. Also does anyone know where I could get an air filter stud, and period air filter for it? Thanks, Brett

BTW the carb is off of a 63'-65' 230 motor, not the one off the original 216, which I don't think has an air cleaner stud. Brett

Brett,

This page might help you confirm the identity of your carb. Late 235/261 engines (pre-'63) had air cleaner studs.

For a stud, buy a piece of threaded rod from any hardware store. Maybe someone else will know what year Rochester one-barrels (on trucks) had the center studded air-cleaners. I would guess 1958-63.

Is the brass filter stuck to the filter inlet nut? If that is the case a little carb cleaner should get it off. They are available at any parts store. Just tell them you want the GM brass fuel filter. They used the same one for many years. I have the air cleaner stud but like Der Man says you can make one out of threaded rod available at any hardware store. If you cant find the filter let me know. I can send one or get the part number.

Thanks for the advice. The filter was soaked again overnite and still wouldn't budge, so after a few hefty whacks it finally came loose. The gasket was completely gone and filter seized to the fitting. But after cleaning I think it is still usable. As for the air filter stud, threaded rod is a good idea as soon as I get an air cleaner cleaner to size it up. Was the original for the 230 an oil bath type? Thanks again, Brett
