Rochester BC Carburator with automatic choke



With the 235 passenger car engine a Rochester BC carburator is stock.And i want to use it because its a new one.

I started the engine for the first time after the remanufacturing and it runs pretty good, but the carburator is not acting as it should do really?

My question is how to install the short straight tube that goes from the carb side towards the exhaust outlet and should catches the heating that effects the carb autmatic choke? Pictures are very welcome.

Thanks Martinius.

Martinus ;

What you need is called a " Choke Stove " , it's a little sheet metal plate that attaches to the side of the exhaust manifold and has a small hole for the tube that goes up to the bi-metallic spring in the choke heating chamber .

If you look up the 1962 passenger car carby section in The Old Car Shop Manual Project OnLine , it'll have pictures you can copy then know what to look for....

Adjust the choke cover in the early morning when it's stone cold , throttle open , turn the bakelite cover until the choke valve _barely_ closes , that's it .

Once it's hooked up and the choke is correctly adjusted , follow the correct cold starting drill : engine cold , depress the throttle to the floor _once_ and release , DO NOT touch it as you crank the engine , it'll instantly start and continue running . of you touch the throttle , it'll die and not have a fast idle .

Thumbs up Rochester BC carburator

[QUOTE=vwnate1;50728]Martinus ;
Thanks Nate

I found the sheet metal plate and make a nice copper pipe that will catches the heating from the exhaust system. I will follow up your advices and see what happens? Its beautifull outside here now, snow is melting and life is just great in beautifull Hov/Norway.

Its nicer working with my old truck then using time looking for the easter bunny to come that i do not believe in anymore?

Have a relaxing easter Martinius.
