The Stovebolt Site Forums The Shop Area Engine Shop Carter on a 230ci I-6

Lots of guys looking and or changing carburetors on the 216 and 235 engines. Anybody replaced the Rochester with something else on an early (65) 230? If so what did you use include part #s please. How did it run and would you do it again? Difficulty installing and/or modifications made? Thanks

Not recommending anything!,but my 65 292 has the mono jet,and works pretty well,aside poor choice on my part tried using china pump piston,and had to use a old school leather cup as bore out of spec

I noticed that the plastic pump piston is standard in most AFB's and two barrels as well. Just removed an hour ago from a from a street rod. In my personal opinion once it has set to long with modern gas not much chance of making it right again. Sometimes a leather replacement can be found. Leather I found will get the right shape and texture. I have a warped float bowl, model "B" that I put a dried out or warped one in with some Carburetor Fog Spray in. A few hours later and good as almost new. Doc

Other options than Rochester, please. Rochester’s have been discussed to death here.🛠

I would think a Carter would be just fine, as long as it is sized and tuned correctly for your engine. I'm thinking Carter YF.

I am running twin Carter W-1 on a 250. I would look for a W-1 ( http://www.thecarburetorshop.com/CarterChevroletW1.htm ) from '41-'48. Mine run really well and are quite tunable.

You may want to look at a 65 Chevy van with manual transmission, 230 engine and manual choke which was equipped with a Carter YF 4145s.
The distributor vacuum advance connection is below the throttle plate on both carburetors so this should work okay.
The Carter throttle arm location is in a different position (forward of intake manifold) to the Rochester (rear of intake manifold).
The Carter throttle arm lowers to open the throttle valve which I believe is the opposite direction from the Rochester (please verify that).
Maybe you can find a picture of a 65 van with a 230 and see how the linkage was done or maybe find an assembly drawing off the Internet.
You may have to convert to a cable accelerator linkage or modify what you have.
Your manual choke cable may need to be rerouted.
You can find used and rebuilt 4145s on ebay but make sure it has all the parts you need (bridge to hold the air cleaner, choke bracket etc.).

Justhorsenround, Carter and Rochester are the same company. A W1, YF etc are the same as old Rochesters. When Rochester could not keep up production they bought Carter, the only difference is Carter is stamped on instead of Rochester. This was very evident with the Carter AFB that was put on high performance GM engines in 1957 on. Doc

Again, I’m not interested in discussing the relative merits of Rochester vs Carter or the history of each company. My question was very simple and adequately addressed by Green_98, Joe H and buoymaker and of course Carbking by PM. Thanks guys.

What kind of guage, where located, multi Vis. or straight wt. oil?
