I have read many positive things about the Carter YF's and negative things about the stock Rochester (even rebuilt). The Roch carb I have is full of soot and grime and has not been run in years. Thanks to all! | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | What year 235 are you installing into your 1950 3100?
What year intake manifold do you have?
If you go with a YF (various versions from 1940s to 1970s), you might want to get one from an engine similar in cubic inches to your (unless you are able to modify/change jetting).
As you noted, Carters are more highly regarded than Rochesters. I have always had/used Rochesters - the one I found on my 1948 216 (in 1969) leaked at the top/bottom joint. My 1954 and later Rochesters do not leak. | | | | | Joined: Dec 2015 Posts: 43 Wrench Fetcher | | Wrench Fetcher Joined: Dec 2015 Posts: 43 | Interesting, the Rochester on the original 1950 216 leaked and ran like crap. The 235 I am using is a 1958 model so I assume the intake is original. If the later Rochesters were better, I might try a rebuild. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | | | | | | Joined: Aug 2012 Posts: 1,214 Shop Shark | | Shop Shark Joined: Aug 2012 Posts: 1,214 | re. Rochesters. I'm batting 2 for 4 in getting a good one.
All 4 that I have experience with are older manual choke models.
1 is the smaller 216 version and the other 3 are the larger 235 versions.
The one I rebuilt on my 49 216 runs flawlessly. I've got approx. 13K miles on it since rebuild and so far so good. No problems with it.
The 3 I tried for my 54 235 have differing problems. One hesitates in the acceleration circuit and I can't get it right, another has vacuum leaks around the throttle shaft and the other has warped body halves and leaks. I was able to make 1 good one but I need 2....
Rebuild kits aren't expensive and always worth a try, buying so called rebuilt carbs can be like buying a pig in a poke, you won't know till you buy it.... And they ain't cheap....
Good luck
